Firefox Support Forum

I want to use the Advanced Preferences (about:config) to select 'Manual proxy configuration' setting. I have been able to set the HTTP Proxy and associated port but I am unable to find the setting in Advanced Preferences that will select Manual proxy configuration. Could someone please help. Thanks

Yes, I know addons exist for it but many work places don't allow installing addons, security wise they can be a concern and these addons have poor UI/UX. I am genuinely considering using Edge over Firefox due to them having better tab groups which I never though I would say. Please implement a simple tab folder, literally just what current Edge has. It is a very useful basic feature and I would really love to have it included in my favorite browser I have been using for over a decade. Thank you.

When I open the application it loads as a small window that I have to maximize to make it full screen. It never used to do this so I need some help to fix this. I've taken a quick look through settings etc and can't see anything wrong...

why do my add-ons keep getting disabled?

ff keeps disabling add-ons that i have used for years and even keep a v. 5 to use the older add-ons and use the latest ff developer to use w/ more modern websites. ff even disables add-ons that worked perfectly well in ff developer and does not even give me the opportunity to re-enable them like i could before.

is there any way to force my old version to let ME decide what i want disabled/enabled?

ever since i was in Portugal, and a repairman needed my phone to access our contract for a car repair, my web pages constantly show up in Portuguese. no matter what i set my page to, and it SHOWS it is set in English, i still keep getting pages opening up entirely in Portuguese..and have to work my way thru to reset it BACK to English.

what  is going on ?

I have noticed that I am unable to access the comments section on the various web sites I visit. I am sure it's a settings issue, however I have not been able to find the setting section. Any suggestions??

When I downloader the Firefox I then try tobrowse a company,etc a page comes up withFirefox logo and a line that has Google and the place for the url/ I cannot get the actual browser to open.

I recently suffered a bug in my PC that led to me having to reinstall the OS. I am now trying to reclaim my session/bookmarks etc from Firefox but I'm not able to sign in on the browser. I'm able to sign in on a web page with my email, but no luck with the actual browser menu. The only option I'm seeing otherwise will be to reset my password, but that will seemingly delete years of important data that I only have on Firefox because I trust it!

Please help! Desperately trying to come up with a solution!

Every time I do something Google-related in my Firefox browser the tab crashes. It does the same whether it is the search engine, Google drive, G-mail, etc... I already ensured my browser is updated, to no avail.

Thank you!

121.0.1 (64-bit) on Windows 10 Professional. I'm a Leo and like long walks on the beach.

For months, I've experienced the Bookmarks menu collapsing (Bookmarks Toolbar, Bookmarks Menu, and Other Bookmarks headings appear but all bookmarks are just gone) and locking up (those headings cannot be opened and closed).

I have finally noticed that this happens when I am using Windows File Explorer to drag and drop files into my Google Drive opened with an entirely separate Google Chrome browser running concurrently with Firefox.

To be clear, I have Google Chrome and Explorer at the top of my desktop, with Firefox running behind them. When I drag a file from Windows Explorer over to the Google Chrome browser, the side bookmarks window in Firefox goes haywire. Close and reopening the bookmarks menu brings it back, but the issue remains.

‘I can't receive outlook mail today using Firefox. I receive message header but when I open it there's no message data. It works fine in Chrome. I can't forward a message it fails to connect to the server. When I try to delete messages it doesn't remove the item. Any suggestions?

I have been having problems trying to access the website 'keepersecurity.com'. This started happening with Version 121. I contacted 'Keeper' about the issue, but nothing they suggested worked. While I am using Firefox as my browser, I also have Microsoft Edge installed and available to use. I accessed the site using Edge without any problems. So I assume the problem is with version 121.
