I've got about 10 bookmarks with links to support pages each about adjusting specific about:config setting to my needs. My job also requires me to change systems lots of times, from Mac to windows to Linux. Is there an easy way I can save my personal about:config changes to a file for easy import on other systems?

Thanks

Hello,

Currently running MacOS Montery but the problem was still occurring on previous versions.

Whenever I use the green top left button to enter full-screen, the app immediately freezes and either crashes or has to be manually force quit. There are no reports in about:crashes and I there has been no success with troubleshooting mode or switching versions of the Firefox application.

Machine Info: MacBook Pro (16-inch, 2019) Processor: 2.6 GHz 6-Core Intel Core i7 Memory: 16 GB 2667 MHz DDR4 Graphics: Intel UHD Graphics 630 1536 MB

Any help towards a solution would be appreciated. Thanks!

Hello Everyone,

After inserting the proxy information, webpages in the container tab refuse to load/connect, I insert the IP address and I've also tried the Fully qualified domain name, using the type://host:port syntax, I get "The proxy server is refusing connections" and "The connection has timed out" error messages.

If I setup the proxy via the settings menu the entire browser uses the proxy server address, I am trying to specify a different proxy server for each container.

I used Speedtest by Ookla. When the broad band was installed, the technician did this without a problem. Today when I tried I was taken to an installation page. After I used the SpeedTest, then my main page was gone and instead I have a bar of Firefox selected options. I've tried to find how this is done so I can set it back but I can't find it. Please help.

My Firefox browser was automatically updated to version 101 today May 31, 2022.

The IMDB home page (www.imdb.com) is now broken. The drop down boxes at top right and left are displaying all their options on top of the web page content. Pages are not loading fully.

This is on a MAC. Safari and Chrome browser work properly for the IMDB page.

Is there a fix for this?

A few days ago Firefox started opening in a small window in the upper left corner of the screen. This problem was earlier also posted by other users. So I have read all these topics and suggested solutions.

This is what I have tried: - removing xulstore.json - compatebility tab in properties - manipulating overlapping squares icon and dragging window to almost full screen - Reinstalling Firfox ( without removing Firefox completely on forehand)

So far nothing resolves this problem.

Please advise

When I put the pointer arrow on a tab to open it the tab background turns black and the type is white. It used to be the opposite and I want to change it back to white background black type. How do I do that? I do not like this change at all. This happened right after your new Firefox update also.

Today I updated my wordpress site to 6.0 and now my gallery isn't working in Firefox. It works in Chrome, Edge, and Android Chrome.

I tried turning off all my Add-Ons, I cleared the cache in the browser and W3 Total Cache, and I deleted the gallery and uploaded it again. None of these things worked.

I don't know what else to do.

Hi dear managers, In Firefox 101.0 i want to clear Saved Passwords from History Menu > Clear Recent History! But in new version of FF it is not there. Is there a way to clear Saved Passwords from that menu instead of Saved Logins... In Settings of FF separately?

Thanks for future advance

I have tried numerous times to copy over the contents of my Firefox default profile folder from a Windows 10 PC to a new Windows 11 PC. I followed all the instructions as far as I know (when either saving or pasting the folder contents, Firefox is off; successfully downloaded and installed Firefox on new PC creating a new default profile which is where I pasted the contents from previous PC's profile, etc.) When Firefox is restarted on the new PC, it is just the same as the new installation -- no bookmarks from the old profile show up, e.g.).

Any ideas for how to get this to work are greatly appreciated. I have a lot of bookmarks and need to be able to access them on new PC. (BTW, this approach worked just fine when I installed a new disk drive on the old PC about 5 years ago and brought all the Firefox profile data over - everything came over as expected. I wouldn't think the fact that this is a Windows 10 to Windows 11 porting has anything to do with it not working -- these are just profile folders.)

Would Synching the two PCs work better? Does Synch just add all the profile and password data on the two PCs together so that each ends up with the total of what was on the two individual PCs and nothing on either is lost? When I looked at Synch on new PC, it was not clear how to get it to point to the old PC - Add a New Device just seemed to point to a phone. Again, any help is much appreciated.

Hello

After the latest Firefox update, 101.0 (64-Bit) for Windows, the text of our website can't be read anymore because it suddenly appears way too bright.

It worked since years before and still works with other browsers.

Is this a know bug with version 101 and might be fixed? Or is there any other problem?

The website is: link text

Thanks a lot, if someone can help!

Kind regards,

Wolfgang

why can't Mozilla updates be downloaded,& installed when I sign off instead of when I first log on? Very irritating to have to wait for updates to be completed.Thank you for taking the time to hear me out

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

• My mail client is completely unaffected and is behaving normally.
• I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
• Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

My ISP is BT (UK) and I have 5 BT Mail email addresses. On the mail log-in page there is a sign-in box where I can choose which email address I wish to open. Unfortunately there are several instances of my main email address. Some with old passwords some from I know not where. I need to delete all those except the current one. I have tried clearing the cache and data but to no effect. The duplicates do not appear if I use a different browser, so it would seem to be a Firefox issue.
