A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Hello Firefox friends o/

Anyone knows how do I make https://yandex.com my default search engine? (in the top bar of the browser). I have attached a screenshot of my settings page. Please have a look at the suspicious lack of an "Add" button 🤔. Despite my efforts, the drop-down menu will not show the available options in the screenshot, you will have to take my word for it, the only available options in that menu are: Google, Bing, DuckDuckGo, eBay and Wikipedia (en).

P.S. The settings page in Firefox must change really often, as I seen so many people suggesting many outdated methods online.

Until a week or two ago, Amazon Prime Video worked without a problem on my Firefox browser. Now I cannot get Prime Video to open any show, nor can I access previous episodes of any show. I tried removing all my add-ons, including all my ad blockers and making Prime Video an exception to the enhanced Firefox browser feature. Nothing worked. Can someone at Firefox fix this problem or tell me why it happened? I CAN use prime video without difficulty on Safari and Chrome.

This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection.

My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?

A sidebar has appeared out of nowhere. I removed all extension on that sidebar and it still doesn't go away. I already have a bookmark bar and extensions at the top bar. I don't want another sidebar at every firefox window. How do I remove the sidebar, please.

I'm visually impaired and had originally used a CSS code to fix this problem, but that was a couple of years ago. I just upgraded to 131.0.3 (64 bit) and evidently, that wiped out all my CSS changes. I tried to use the about:config code to change it, but it no longer works. I managed to increase the icon size a little by changing the density to normal, then back to compact. Even on normal, it was all too small.

I don't want to use another profile, because every time I do, I lose so much that it takes me hours to reinstall it all.

Is there an easier way to do this? I've tried a couple of things suggested online, but they were old settings suggestions, and they no longer work either.

ALSO, I now have to use F11 full screen to be able to perform anything on the toolbars. Before this update, I could just move my cursor up to bring the toolbars down, and use the back arrow or refresh easily. Now, the toolbars immediately go back up and I have to use F11 to do anything. How do I fix this?

TIA for any help you can give me.

This is the link. I can't send animated images as the text is too small, so I'll describe it instead. It's so hard as a loyal fan, I'm crying.https://www.bilibili.com/bold text。There is a bug. Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?

I am a bit confused about how to keep updating FF on my Windows 7 PC, given that after March my current version (115.17.0esr) may not work as intended. Until now I've always updated manually by downloading a small 343KB installer file that updated FF without changing any of my settings, logins and bookmarks. Hoping to simplify updating, today I set updates to "Automatically install updates (recommended)" with sub-option "When Firefox is not running". But just now a FF notification informed me it was unable to update automatically and provided a link to https://www.mozilla.org/en-GB/firefox/enterprise/?reason=manual-update. From the dropdown there I chose "Windows 64-bit" > "Firefox Extended Support Release (ESR)". The download is a 64MB file.

Since this seems to be a new installation and not a simple update, can I be sure it won't overwrite my current version and leave me without settings, logins and bookmarks?

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

I currently can't stream anything, and this keep getting this message: Widevine Content Decryption Module provided by Google Inc. will be installed shortly,but it never installs.

I have a macbook air and am currently running macOS Sequoia version 15.0.1.

I tried uninstalling and reinstalling, removing extensions, clearing cache and data, unchecking and then checking back again the reproduce drm protected content but nothing has worked.

Hello! After a clean install of Windows 11 24h2 Pro, Mozilla Firefox is unusable. It takes about 2 minutes to load a page which is abnormal. I remember I had the same issue when I first installed Windows 11 23H2 Pro and that was resolved somehow but it was 2 or 3 years ago and I've no idea what the solution was back then. I've tried some basic stuff including Test suggestion which of course didn't resolve anything as almost all of them are referring to cleaning cache, reinstall Firefox etc and it literally has nothing to do with my situation. Any solutions?

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

With Firefox 135.0 i cant reach google.com but google.se i can.

I make daily images of C: and today i managed to go back one day to 2025-02-06 but accidentally chooses 2025-01-06 and with the older version of firefox i could reach google.com

I have tried to delete cookies. DNS over HTTPS off. No proxy in connection. Add-ons off but to no avail.

At some point Firefox stopped allowing me to drag tabs or bookmarks around. This includes moving tabs around in their order, dragging a tab into a new window, dragging tabs into bookmarks, moving bookmarks around in the browser. I can't drag them around in 'manage bookmarks' either. I can still open and create bookmarks; they are simply much more difficult to place where I want them.

I believe this happened with the last update but it's not a feature I use all that often so it could be older.

I have opened Firefox in safe mode and had the same issue. I have turned off the computer several times since this began.

Any help would be appreciated.
