All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

I accidentally blocked a web site that I need. I have followed all of the instructions to unblock (creating a master password, etc) but it does not work. I need to get this site unblocked as soon as possible.

I've just completed building a brand new PC and installed Windows 10 on it. I'd always used Firefox on my old system specifically for the Amazon Review Checker that automatically popped up in the browser when I opened an Amazon Product Page.

I don't understand why, but this is not happening on the new computer. I've double-checked "about:config" and enabled everything to do with "experience2023" and it still won't work. I saw mention in other support posts that there is supposed to be a $ dollar sign icon in the address bar, but it is not there. I tried manually installing the extension but that just adds links to the Amazon page, that open in a new tab when you click them (I've since uninstalled the manual extension).

I'm not sure why I can't seem to open the integrated Review Checker, can anyone help me? Thank you.

I can only use firefox for 90 minutes at a time, before the entire system crashes.

Since the last couple of updates, the infamous memory leak issue has gotten significantly worse. Now 30 minutes of use with no add-ons sees the memory use swell to 13 GB, crashing the system. Sometimes windows 10 crashes, sometimes it just kills firefox.

The thing is, when I check about:memory, it says firefox is only using 1.5 GB. However task manager says 13 GB, and if I close the browser, suddenly 13 GB memory gets freed up.

Does anyone have any idea why there's such a discrepancy?

I'm expressing a strong dislike for the very shortened list of paper sizes in Firefox in the Print function.

One big reason I use Firefox over Chrome and MS Edge is the long list of paper sizes. Now the list is a small fraction of what was there. And how many people know what sizes are the likes of A4, B3, JIS-B4. It takes extra time to figure out what works best.

The old list with Letter Plus, Letter Extra, Legal Plus, etc. was MUCH MORE useful. If I were to eliminate anything, it would be the meaningless A5, B5, etc.

At least give us an option of the old or too short new list of paper sizes.

Hi!

I'm not sure if this is a Firefox problem or not, but every time I try to go the Facebook website I get this error:

"Sorry! Something went wrong :("

And it has been going on for weeks. Sometimes it works in the evenings (UK time), which seems weird but it is rare. I tried troubleshooting mode and it made no difference. Facebook is my sole means of contact with some people, including one or two students (I'm a tutor). I also tried to install the newest version of Manjaro, but it made no difference.

Also, I cleared the whole history, and do that at the end of each day anyway, so that is not a fixer.

The reason why there is any doubt that it a is Firefox problem is that it also happens with Chromium but without the occasional successful connection.

Does anyone have any ideas? And is there any other information that it might be useful for me to provide?

(Firefox 131.0.3 and up to date version on 12/03/2025) (Manjaro 24.1.1 and up to date version on 12/03/2025)

Supplementary note: I won't be able to use Caprine as an alternative access as it has effectively been obsoleted due to it being dependent on Electron29, which won't build for some obscure reason. And no, I don't have a smartphone.

Thank you kindly,

Oliver.

I've got full-screen-api.ignore-widgets = true, so that I can use the f11 key effectively as a "hide-the-toolbar" button. this works nicely since I can still use my window manager's fullscreen shortcut to actually go into fullscreen.

the problem is, whenever I do that, firefox detects the change and then shows/hides the toolbar again accordingly. just wondering if there's any way to stop firefox from detecting fullscreen changes?

I naively turned off exit-on windowOpen & windowRaise, but that had no effect.

any help is appreciated.

Hello,

I have tried several times to adjust settings to get audio. I have audio on my other laptop with Firefox but not this one. I was going to un and then reinstall but Mozilla suggested I try to refresh. It doesn't work. Very frustrating. I missed out on a meeting because of this.

With the updated version of Firefox (136.0.1), the menu items that were located at the top in the menu section used for modifying documents no longer are visible. How can I get those back in place?

1. My account says that my 2-step process is disabled. 2. But Gmail asks for it, but doesn't recognise the pin code number when I enter it. 3. Can someone tell me the way that I can find where my pin code is recorded. 4. So that once I've found that, I could try changing it so see if that would fix the problem.

I use a lot of containers (love this extension!) and have an improvement suggestion.

It would be helpful if the entire tab was colored, rather than just the little line at the top. I have a hard time seeing the line and distinguishing between similar colors.

For context, I have to log into multiple email and website accounts for work. The tab descriptions are often the same (for example, I'll have 3 or 4 google accounts open and they all say "Gmail" or "Admin console") so I have to click on each to find the right one since the colored line is hard for me to see.

For some time now, firefox literally has NO horizontal scrollbar, even on sites when it is clearly needed.

How do I make it visible? Is it a Windows 10 & 11 thing?

Also, before anyone suggests it, several posts online mention to go to Settings > General > Browsing > Always show scrollbars. These posts are over a year old, however, and this option DOES NOT exist.

Thanks in advance.

Hi,

On my "new tab" page, the "add a shortcut" button is missing. I can pin, unpin, move, and dismiss shortcuts freely, but only those which automatically appear. Unfortunately the page I'd like to pin is not in the auto-generated shortcuts list (even expanded to 4 lines). It is in my recently bookmarked pages, but the context menu there does not allow adding it to the shortcuts. I use Windows, Nightly 138.0a1 (2025-03-13) (64-bit).

Thanks for any help, Pat

Using Imac m3 and Sonoma and latest version of Firefox. An instructional site I frequent contains videos hosted both on You Tube and on Kajabi. The videos from Kajabi show a blank space where the thumbnail would be while the YT videos appear and play fine. However, when I switch to Safari the videos appear. Sounds like a firefox glitch but I can't figure out which setting to change...if it is a settings issue. Any suggestions are appreciated. Thanks

I love using the sidebar button (not the permanent vertical sidebar, but the button in the main toolbar that pops up a sidebar when I want it).

However, I want it to default to Synced Tabs, but it always defaults to Bookmarks whenever I restart Firefox. I already have a bookmarks toolbar, and don't need them in the sidebar.

Is there a setting somewhere that would let me set the default to Synced Tabs?
