I can no longer pin extensions/add-ons to the toolbar. My interface does not look like the one in the help section. I don't see a gear, I see three dots. And when I click on the three dots I don't have the option to pin to toolbar.

I am using Firefox 147.0.4 on Mac OS 26.3 Tahoe.

Firefox says versions earlier than 115.13 will be impacted by the certificate expiration. I've updated to 115.21 My add-ons are still disabled. https://support.mozilla.org/en-US/kb/root-certificate-expiration

It seems many don't know or haven't noticed but merely running an esr branch (rather than a developer edition) will also give you the option to enable add-ons with expired certifications via about:config.

Anyway, the "legit" way isn't working.

How do I move an addon from the TOOLBAR into the PUZZLE PIECE list? I can get them OUT onto the Toolbar.

Also, the Customize Toolbar / overflow menu won't accept anything, the addon just pops back out when dragged from the Toolbar.

The moment my version of Firefox auto-updated to 141.0.2 (64-bit), all of my extensions disabled. There is no option to re-enable them and no indicator of why they are disabled.

I found that switching to a new profile allows them to work, but of course that's not really an option; I have huge amounts of custom stuff in eg. Greasemonkey that I cannot afford to lose.

What can I do to preserve my extensions without losing things like Greasemonkey scripts? Again, deleting them and reinstalling them is not an option if it would lose their individual configurations.

I have two accounts n Youtube and the same video downloader app installed. in the first account I cannot download any video and i get the message "no links ere found". if I switch to the second account in the same video, I have no problem and I do download the video. what can be the solution to the problem?

I installed the extension with the first account which I use as the primary one. at the beginning and for a few months it worked fine and suddenly it stopped working. I didn't do anything. I changed to the second account for other reasons, and I noticed that the downloader works without any problem.

I have just had to replace my PC following a bit of a disaster with my old one. The new PC has Windows 11. As usual I downloaded Firefox as I always use this. Somewhere in the installation of Firefox I must have been asked about blocking ads, but I don't remember. Now all ads are blocked, which I don't mind, but some sites are asking me to disable my ad-blocker if I want to use their site. Mostly I don't but there is one I need to use, so I would like to add that site as an exception, but I cannot find any mention of any ad-blocker in settings. Where do I find this? and how do I add exceptions?

The only add-on that I have in Firefox is the 'Privacy Badger' which could be the problem I suppose, but I can't see the website listed in the ones Privacy Badger is blocking.

Any help would be appreciated

A non-profit I support suggested the "Give Freely" app. The extensions search in Firefox did not find the app. Is it known and trusted by Mozilla? It's privacy policy suggests it functions like most other apps: it collects all the data it can, and allows the third parties that support their functions to collect all the data they can. The third parties can do whatever they like with my data.

Thank you,

Dear Firefox Support Team,

I am reaching out regarding an ongoing issue with the NordPass extension on Firefox. For over a month, I have been encountering a source map error when attempting to log in using the Windows Hello PIN code.

The specific error message is as follows: Source map error: Error: NetworkError when attempting to fetch resource. Resource URL: moz-extension://23234j35k5j439434932u2j32l/css/biometrics.css Source Map URL: biometrics.css.map

I have already contacted NordPass support, but unfortunately, I have not received a resolution. I am hoping that your team can investigate and address this issue.

Please let me know if you need any additional details.

Best regards, Alexander

When I publish an extension on Chromium-based browsers, I can select the markets/regions in which I would like my extension to be available. I cannot find this option in Firefox add-ons. Am I missing something, or should I assume that the add-ons are available for every region in Firefox?

How can I stop advertisers from changing my 'Settings' fields 'Home page and new windows' to their URL which brings up their page before I can enter my password? I'm on Linux Desk Top.

One of if not my most favorite addon "context search" has recently been flagged as violating mozillas tos. I'm talking about this one: https://addons.mozilla.org/de/firefox/addon/contextsearch

I am unable to find further explanation or the exact reason for this decision, but I am able to activate it again at my own risk. Seeing as I don't know what the problem is, I am hesitant to do so. Could someone explain what the issue is and if it's safe to continue using that addon? Am I or is my personal information at risk, since I have been using the addon regularly?

I have just got a new laptop and installed everything in relation to Firefox onto it. I have used the Nordpass extension for a couple of years and on the old laptop this is version 5.23.13 updated 16/10/24. On visiting the add-on and extension site today there is only a legacy version 4.33 updated 2y ago which clearly no longer works. Where has it gone. Clearly I am going to ask the same question of Nord, but I hope you can help.

I did a new Windows 10 install yesterday. I then added my favourite apps.

When I got Firefox installed, adjusted the settings and added my extensions (most of which I've used for years), I found a glitch.

The icons for AdBlocker Ultimate and LastPass do not show up in the Customize Toolbar menu. I keep both of these on my toolbar in the past.

I've tried restarting Firefox several times and, finally, tried running it in Troubleshoot Mode. The last, it seems, doesn't allow the use of extension.

So ... please help!

Well, well, well. Latest Firefox update and what did you folks send along to take over my PC screen when I log-in? This: https://getadblock.com/en/update/latest/?f=f&version=6.31.1&u=68uu84zt49066849&bc=3072&rt=0

Clever, clever, clever aren't you folks?

1. I have NEVER downloaded "adblock" 2. "Adblock" cannot be found in the PROGRAMS listed on my PC, so no way to "uninstall" your uninvited, unwelcome, unneeded bit of buy-this-buy-this-buy-this angling. 3. "Adblock" cannot be found on a search of the registry. 3. What a pathetic approach, Firefoxers!

GET RID OF IT FROM SHOWING UP ON MY COMPUTER SCREEN WHEN I OPEN FIREFOX! NOW!

The Firefox Translations add-on has been discontinued and no longer works. As a foreign language learner, I found it very useful to open the Firefox Translations popup, enter some text, and have that text translated locally. Is there an alternative that has the same functionality?
