Hello Firefox You are very good I use Firefox since a long time I wish that Firefox create an addon to enable us to colour every tab in a session where that colour of the tab can be saved for this single tab and we can change the colour of the tab according to our browsing meanings, because we tend to give the colours meanings so that we categorise the coloured tab in its place without changing the ordinary and usual user interface, that will make browsing more funny and productive, that's it

Thank you Firefox you are very good

Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

I guess i may have downloaded something not good. Because I keep having to redo the time on my laptop. Then I see under the plugins a warning that it wasn't supported. Like it's not to be trusted. I can't find it now. But I been having to go in and change my time zone every log in just about. Arghhhhh. Help Wizard!

Sir, I am unable to add 'Grammarly' in my Firefox browser extension. Every time, the following message appears: "The connection has timed out". Please look into it. Regards

Hello, I'm having problems running the Synology C2 Password extension in Firefox and the Synology support engineer wants me to send them a "System Diagnostic Log". In detail, they asked me to do the following: 1. Launch Support Center on your device. 2. Go to Support Services. 3. Click Generate Logs. Is this something you do in Firefox, or is this generated by the computer operating system? I'm running a MacBook Pro with macOS Big Sur 11.5.2 and Firefox Version 136.0.4. Thank you very much to whoever answers my question. Cheers.

Hello, I occasionally go into the Firefox Extensions Manager and request it to check for updates. Today, I happened to notice that my extension for NordVPN was quite old (Version 5.2.2), and I was not able to get it to update. Therefore, I removed that extension and downloaded it again, which installed the latest Version 5.6.2. Is this a bug in Firefox? I am running Firefox 151.0.4 on macOS Monterey 12.7.6. Thanks!

OK, for me, this has always been the 'go to' browser of choice.... until recently...!! I've tried a whole heap of browsers, some open-source derivatives, some based on gecko, you name it, I've tried it.... for Mac and for Windows, although I won't put some of those tripe PC ones on my beloved Mac, and there in lies the problem...!! My Mac Pro is a 17yr old quad which is still quick by today's standard and I run El Capitan as it won't upgrade anymore, running Firefox v78... I don't it to be running the most up to date b'cos I'm not doing anything special to warrant getting t'morrow's browser today.... my problem is.... some of the extension which made this browser run faster have been stopped due to verification issues...!! How did these extensions make to the Add-ons if they were never verified in the first place as they were in use for a while before use was halted...!! Now, I get stupid pop-ups randomly, along with salacious material asking my to join suggestive websites and worse, some of which bounce to 'other' websites when you try to delete them...!! Do you not have ways of verifying these extension before they hit the Add-ons page...?

I have had the YouTube Nonstop extension for a few months. It was great. It let me play playlists without stopping every few songs. Then today it quit working.

I turned it off and back on but that didn't work. I looked for an update but the last one was 2 years ago.

I haven't tried removing it and reinstalling it. I guess I will do that. Anyone have any ideas?

I see people communicating with the developer on the App store, but I can't find out how to do that. I don't see a link to the developer.

Any help would be appreciated.

Hello,

My university requires me to logon to use campus services every 24 hours. Upon expiration of the logon credential after the 24 hour period, a logon window will prompt to re-enter credentials. The problem is that it will continue to prompt log in with new pop up windows every few minutes so if I don't log in, for example, over night, I'll wake up to hundreds of log on window pop ups. This creates system wide slowdown due to memory resources being maxed out. I can't enable universal pop up blocks as the systems I require use pop ups and having to open each pop up manually does work in my workflow. Any solutions? Thank you!
