I know this is old news by now, but I was not sure how to activate vertical tabs on all of my browsers. It certainly is not obvious, so I wanted to include the instructions here in case anyone else wants to try it out.

Type about:config into the address bar of Firefox. You'll be greeted with a warning that you are accessing advanced settings - click "Accept the Risk and Continue." Search for the boolean preference sidebar.verticalTabs and set to true. That's it! Enjoy your vertical Tabs!

Edit: You may also need to set sidebar.revamp to true if it is not already/automatically set.

Chrome and Edge make it simple to 'install' pages, so they're easy to pin to the task bar. PWAs for Firefox gives that capability to Firefox, but it's a bit brittle, and breaks easily if Firefox updates. It's broken again for me tonight and the usual 'reinstall this reinstall that' hasn't fixed it.

In my opinion Firefox took a significant backwards step when they killed that feature years ago.

I appreciate I might not be the target audience for Lemmy since I'm half Windows half Unix, and a Gmail / Keep / Calendar / Facebook / Messenger user.

When you have the choice of multiple addons/extensions that can perform a certain task, is there a way to monitor their system resource use? To select the one which is the leanest.

I am sometimes using firefox on low-end devices. I feel that certain extensions are using more/less resources. But what's the truth?

In linux system/task monitors, you can see processes "WebExtensions" running beneath firefox. Is this reporting extensions as name suggests? If so, is there a way to correlate them to specific add-ons?

Would also like to be able to know about what extensions are doing "in the background" vs when you are actively using them.

This is about desktop versions of firefox, not mobile.

Hi r/firefox 👋,

The address bar is one of the most prominent areas in any browser, and Firefox is no exception. Understanding its importance, the Firefox team has been working on a set of complementary features designed to improve discoverability and security of the Firefox address bar.

With this set of features landing in Firefox Beta 135, we need your expertise to help us test these enhancements by participating in this campaign, which will be live on January 9th! 

The top 5 contributors will each receive a $50 voucher to shop at Mozilla’s swag stores as a thank-you for your efforts. 

Have any questions about this campaign? Join us on Matrix or comment down below!

Is there a way either through an add on or through settings to force a website shortcut to open as a web app? I have issues with a lot of sites that are designed as web apps. I've even worked with developers who said that the website is designed and meets all the criteria of a web app. Firefox Mobile seems to not recognize or disregard this information sometimes.

The sites are perfectly functional, but there are benefits to running them outside in their own window. It affects things like the persistence and memory being able to switch quickly between tasks, etc. I could obviously do this through a different browser that is purpose built like Hermit, but I would like to do it in Firefox if possible. I don't want to have to install a bunch of different apps on my phone just to run other apps.

I'm not a developer, but it really seems somewhat arbitrary, which apps, Firefox decides are valid web apps, and I would rather be able to make that indication myself.

Solution: I just needed to disable Firefox Color in about:addons.

I set a theme with Firefox Color, I tried changing the theme in settings to light or dark but neither work. I'm wondering if there are other ways to do so in Firefox that I could try. I'm on zen browser which is why it may not have worked.

2 things, (both visible in the image):

1. Right clicking now has the option "copy without site tracking" greyed out, and
2. the context menu has an "Add Youtube" option.

Anyone know how to get rid of either, or preferably both behaviours? Ie: I want to be able to 'copy without site tracking' and get rid of the 'add youtube' prompt.

Solved: It turns out I needed to add https:// to the redirect URL. I now edited the redirect to be this:

{
    "createdBy": "Redirector v3.5.3",
    "createdAt": "2024-12-25T00:25:04.487Z",
    "redirects": [
        {
            "description": "sh.reddit.com submission page",
            "exampleUrl": "https://old.reddit.com/r/firefox/submit?selftext=true",
            "exampleResult": "https://sh.reddit.com/r/firefox/submit?selftext=true",
            "error": null,
            "includePattern": "https://.*?reddit.com/((r|u|user)/.*?/submit.*)",
            "excludePattern": "",
            "patternDesc": "",
            "redirectUrl": "https://sh.reddit.com/$1",
            "patternType": "R",
            "processMatches": "noProcessing",
            "disabled": false,
            "grouped": false,
            "appliesTo": [
                "main_frame"
            ]
        }, 
    ]
}

Using the Redirector addon, I wrote a redirect from a Reddit submit page to the new new Reddit submit page but it doesn't work when I go to https://old.reddit.com/r/firefox/ and click "submit text", it just takes me to https://old.reddit.com/r/firefox/submit?selftext=true despite the link working in the example box.

Reproduction: Install the addon, save the following as a json file, click on addon icons and select "edit redirects", then click import to select the json file.

{
"createdBy": "Redirector v3.5.3",
"createdAt": "2024-12-22T15:43:42.356Z",
"redirects": [
{
"description": "sh.reddit.com submission page",
"exampleUrl": "https://old.reddit.com/r/tds_roblox/submit",
"exampleResult": "sh.reddit.com/r/tds_roblox/submit",
"error": null,
"includePattern": "[a-z]+?:\\/\\/.+?reddit.com\\/((r|u|user)\\/.+?\\/submit.*?$)",
"excludePattern": "",
"patternDesc": "",
"redirectUrl": "sh.reddit.com/$1",
"patternType": "R",
"processMatches": "noProcessing",

"excludePattern": "[a-z]+?:\\/\\/.+?reddit.com\\/((r|u|user)\\/.+?\\/submit.*?$)",
"patternDesc": "",
"redirectUrl": "https://old.reddit.com/$1",
"patternType": "R",

}
]
}

I often open articles/wiki pages wanting to skim them for information, and sometimes Ctrl+F is not enough to quickly find what I'm looking for. I wish I could type in prompts like "What city did it happen in?" (or just "city"), or eg. "public response", and it would highlight the phrase/sentence/paragraph of the article that is the most relevant. I imagine it's probably possible with LLMs today. Does anyone know if an extension like this exists yet? (if not for firefox then for chrome for the time being)

Your tech choices matter more than ever. That’s why at Mozilla, we believe in empowering users to make informed decisions that align with their values. In that spirit, we’re excited to announce our partnership with Ecosia, a search engine that prioritizes sustainability, and social impact.

Did you know you could choose the search engine of your choice right from your Firefox URL bar? Whether you prioritize privacy, climate protection, or simply want a search experience tailored to your preferences, we’ve got you covered.

Ecosia goes beyond data protection by addressing environmental concerns. Every search made through the search engine contributes to tree-planting projects worldwide, helping to combat deforestation and regenerate the planet. Ecosia planted over 215 million trees, across the planet biodiversity hotspots, making a tangible difference in the fight against climate change. Just like Mozilla, they are committed to creating a better internet, and world, for everyone.

Together, Mozilla, Firefox and Ecosia are contributing to a web that is more open and inclusive, but above all — one where you can make an informed choice about what tech you use and why. Your tech choices make a difference.

As Firefox and Mozilla continue to champion user empowerment and innovation, we invite you to join us in shaping a web that makes the world better. Together, let’s make a positive impact — one search at a time.

I don't want text to be unloaded from pages because then I can't see all the results on the CTRL F box. This happens on Discourse forums and New New Reddit (its too bad they removed the 2018 redesign).

Firefox is removing the Do Not Track privacy setting from version 135 onwards. The change is already live in Nightly. Mozilla recommends using the Global Privacy Control setting as an alternative to avoid being tracked.
