Hi,

I seem to be having a really odd issue where each time I restart Firefox, recent addons I've installed will not function or appear in the Add-On drop down menu (despite being meant to appear in such), despite being enabled and still being shown as such when I check settings. They only become visible and functional when I disable and re-enable them.

I've just discovered the same thing seems to happen in reverse too. I recently disabled ClearURLs due to a bug it was causing in Google Drive, yet it appeared in my Add-On drop down menu after restarting. Checking settings showed it to still be 'disabled'.

Things I've tried:

• Restarting both Firefox and PC.
• Uninstalling and reinstalling the effected Add-ons
• Deleting my extension*, compatability.ini and prefs.js files - erasing all my add-on settings yet still not helping. This is the main thing I've suggested on forums like this with similar questions, but has not helped.

It seems to only be effecting the most recent set of add-ons I installed over the last week, as if Firefox keeps trying to work with the Add-on settings I had at a previous date. I've seemingly had some cases where the extensions disable or are uninstalled entirely but I'm not sure this is related, as I think it only happened once.

I suspect it's not to do with the new extensions themselves, given it's effecting all the most recent ones, but I'll list the ones I've seen it effecting here regardless:

ClearURLS (not recently installed, but as mentioned showing similar reverse effects) Undo Close Tab YouTube NonStop Privacy Badger History AutoDelete Don't Accept Image/Webp Decentraleyes Xkit Rewritten Disconnect AI Grammar Checker & Paraphraser - LanguageTool &udm=14

As you can see I recently installed quite a few anti-tracker type extensions which probably overlap in function, mainly just to test them out, so it could be connected to them I guess... but seems unlikely.

Thanks, Matt

I have a IP intercom that only works with Firefox 127.0.2 Now Firefox automatically upgrades to the latest version and I'm unable to prevent this. I'm unable to manage my intercom with the latest version. How do I turn off automatic updates.

Got this error message on recent update and now Firefox doesn't work at all. Platform Version '131.0.3' is not compatible with minversion >= 131.0.2 maxversion <= 131.0.2

Hi, I used Firefox browser at work since it had the best add-in for tab groups (Simple Tab Groups). Unfortunately browser is not supported any more. Is there a portable version that can be run without installing, from Mozilla.

I read a post that indicated it was available from PortableApps, but am not conversant enough to know that it's 100% safe. Believe that it was able to be updated as well.

I have loved FF desktop browser since I started using it per my boss in 2003. But I am so tired of the fact that EVERY SINGLE TIME you put out an update it breaks my access to the bank. EVERY SINGLE TIME. I waste HOURS reading articles, calling the bank IT dept, chatting with people who are on 3 calls at once, only to hear them tell me to "just use chrome." I clear the cookies, clear the cache, reboot, follow all the prompts in the settings and THEN the damned bank server doesn't recognize the device so it forces yet ANOTHER password change. It happened again TODAY and it makes me so sad but I cannot do it anymore. I am STILL now (going on 4 hours) trying to access the billpay page @ Xantanderbank. (ahem, secure codename) I am forced now, by this craziness, to use the imbecilic duckduckgo which is A) and offensive name and b) you KNOW it nowhere near the product you have built but I CANNOT DO THIS ANYMORE. Thank you for the time it takes to read this diatribe. I appreciate it.

Latest update, 4. oct. Using Firefox Developer Edition. Closed the browser window for the day, and then on opening again it had updated, my entire toolbar, and also icons where the tabs are, are just gone - including the "+" icon for creating a new tab, along with the bookmarks bar having vanished. Picture added below.

It seems like the bookmarks bar is still there, you just can visibly see any bookmarks. Tried adding a new bookmark, but nothing appeared.

How can I fix this?

After an update of both macOS (to macOS Sequoia 15.0.1) and Firefox Developer Edition (to 132.0b3 (aarch64)), the Bookmarks Toolbar stopped working. The same issue appeared on my Windows PC.

Bookmarks toolbar is visible, I can show and hide it but it does not display any of my saved bookmarks. Luckily, they were not deleted and I still can access them via Bookmarks Menu, which is less than optimal.

The Drag&Drop functionality does not work either. When I grab the opened Tab, drag it on the Toolbar and release it, the Tab gets opened in the new browser window and it's not saved.

I'm using Firefox Developer Edition 132.0b3 (64 bit) which I downloaded just a few days ago. Already, there's an update for it, to version 132.0b4. Each time I open Firefox, there's this popup that tells me that there's an update available and that I need to download it. I'm using Linux Mint 21. I've already visited about:config and changed app.update.silent to true, changed app.update.manual to true, and changed app.update.url.details and app.update.url.manual to fake hyperlinks. Despite doing this and despite restarting, I'm still prompted about the update available every single time I open Firefox. Could someone kindly tell the specific developer who implemented this annoying feature, to please provide an option for Users to not be bothered with such popup notifications?

ps: Why does this website have a white background and not allow extensions to change it to a dark background? I have Dark Reader extension installed, but it says that it cannot make changes to this website. Even uBlockOrigin is unable to. Please either allow extensions to change the background, or at least change the background color of this website to dark. It gets strenuous on the eyes to keep staring at a bright white backgrond.

After a windows update I get the following message when I try to open Firefox: The procedure entry point ?ToLogLevel@mozilla@@VA?AW4LogLevel@1@H@Z could not be located in the dynamic link library C:ProgramFiles\Mozilla Firefox\xul.dll Then I get Couldn't load XPCOM

I tried uninstalling firefox but it just hung. I restored it to before the windows update but still got the same message

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

Running Firefox on macOS Sequoia 15.0. Afternoon of Tuesday, 8 October, Firefox abruptly ceased loading any pages. I eventually learned of the malware incident and downloaded Firefox 131.0.2 last night and overwrote the existing file. It worked for a brief moment, then also ceased functioning. Have downloaded 131.0.2 several times now, with no further success. Currently dead in the water with Firefox, and stuck with Safari. :(

Hello, I have an issue with installing other extensions. Every time I have been trying lately it keeps prompting me to check my internet connection. I have checked it, it is fine, going strong, supporting constant gaming with no lags or spikes, I have no VPN active when trying to install. Are extensions no longer supported by newest mozilla version or something? It is the only browser with this issue and I will switch the main browser if I cannot get extensions to make life easier.

Currently on 131.0.3. Started having this issue around the time 131 dropped.

I press Ctrl-shift-O and bookmarks manager won't open. Bookmarks manager opens normally if I use the menu to open it. Keybind won't work in troubleshooting mode so I know it's not an addon, and the hotkey works fine on other computers with Sync enabled so I know it doesn't have to do with my synchronized settings. Also won't open with a fresh profile so I am very hesitant to reset all my settings.

I use this keybind multiple times per browsing session so it has had a major impact on my usage. Not sure what to do. Please help!

I'm going to try a graphics driver update in the hope that helps. This is on Windows btw.

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

Hello, could you please let me know if updating Firefox as suggested (version 128) will be compatible with my iMac OS X Version 10.9.5. Thank you very much. Kind regards AS.

We are in an enterprise environment and for years we have had disabled automatic updates.

Firefox ESR 128.2.0 has been deployed with defaults and these settings have been configured to override previous settings.

Computer Configuration > Administrative Templates > Mozilla > Firefox

- Custom Update URL = Disabled
- Disable Update = Disable
- Application Autoupdate = Enabled
- Background updater = Enabled

We also have a system proxy configured.

Updates do work if someone goes to Help > About Firefox.

Looks like the update interval is once every 7 hours but how is this triggered?
