I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

Windows restarted to update and all my 100s of tabs are lost (setting me back days of work!)... Firefox is set to always reopen previous tabs, but it didn't work. Recently closed tabs/windows are blank. The Restore Session page - about:sessionrestore - doesn't restore and lists no previous windows/tabs. I went into my sessionstore-backups folder and grabbed a previous.jsonlz4 that has some data but am not sure what to do with it.

Please help! This is a devastating loss of information, as I use my tabs as a to-do list and had many in-progress projects with resources that I cannot all recover just through history.

On my computer Firefox ask for the master password every time at startup. On other computers in my family, Firefox only ask for the Master Password when accessing a site with a password. I tried : - to disable than reenable Master Password - start in SafeMode without success. How can I solve my issue ? Thanks in advance for your help

There should be a feature where you can copy the link to particular text on a webpage (much like when you click on a Google result for a certain part of an article). Where do I suggest features for Firefox?

I am trying to access websites that use three.js. When I initially start, the website runs too slowly to be usable, but if I tab out for some time and then tab back in, the website runs at normal speed for a bit before slowing down again. I cannot find any solutions to this problem nor anyone else who had the same problem as me.

OS: Windows 11 Home 23H2 (22635.3720) Firefox Version: 126.0.1 GPU: GIGABYTE NVIDIA RTX 4060 Ti 8GB GPU Drivers: Game Ready 555.99

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

Hi, Since the update today to 127.0 My sidebar bookmark will not load when I open Firefox. Here is what I have done so far,

Uninstalled Firefox and use the restore on reinstall. didn't work deleted the xulstore file in 3 location. didn't work Removed Firefox using Revo Uninstaller and installed from the local setup file. didn't work Uninstalled ad-ons that used the sidebar, IE Video DownloadHelper, Sync my account, and tryed the step above again. didn't work I use Revo again and did a search for any firefox file, deleted old firefox folder on desktop and any file I could find with a link to the browser. Reinstalled from local file.

When Firefox started this time there was no profile to log in my account "" password etc "", I did a test and the sidebar was working correctly. I then activated my account and the side bar stop working on restart. Not that I did a sync after removing a few ad-ons, see pic for left addons.

we did an update and having issues connecting to our Emr keeps saying not secure website but it is firefox is blocking us can someone call me [removed phone# from support forum] Nathalie

When I click on any link, Firefox opens a new tab but the site will never come up.

I've tried Troubleshoot mode and refreshing Firefox but something in one of the recent updates has caused me to not be able to click on any link and have it open. Troubleshoot mode will solve the problem for a couple of clicks and then the problem returns even while still in troubleshoot mode. Firefox has become unusable at this point but I'd like to go back. Please help.

When logging in to the online bank at DNB with Bankid, this error appears:

"A communication error has occurred. We are experiencing a communication error between your browser and the user site. The reason may be slow internet or problems with your browser. Try again in a little while. You can also try to delete cookies and browser data in your browser or try a different browser. Error code BID-5000 Reference DXP4VKOE Date 12/06/2024"

No other browsers show this error. I've tried Edge, Chrome, Vivaldi, Brave, CC Cleaner. The error starts after version 125.0.3. Today a new version 127.0 arrived. The same error appears.

I have uninstalled the latest version and reinstalled version 125.0.3. Then no error message appears. I have deleted cookies and browser data, but the error message persists. To your info, I've tried also on other PC's and the same Firefox version, and the same errormessage appear.

I look forward to you having a solution to the problem, otherwise I will have to use browsers that do not show this error. As I prefer Firefox, I don't want to use other browsers. But if the bug can't be identified and fixed in newer versions, I'm not happy with firefox and will use other browsers..

If I open a second tab on the screen it says the connection has crashed and keeps doing it if you try again. If you reset it resets Firefox including the other tab.

Hi Guys,

This is a recent hiccup and only seems to affect Firefox 126.0.1 & 127.0 (I'm running Win64 EME-free):

I have a HTML file which displays images from various weather-cam websites, using the HTML "img src=" tag.

On previous versions of Firefox all was fine, however since 126.0.1 one image in particular will not display - it simply shows a broken image place-holder. Using MS Edge and Chrome, it displays correctly.

This is the image in question:

http://119.17.143.158:8777/Streaming/channels/102/picture/?auth=U1BDRzo1NG5keXAwMW50IQ==

I suspect it's something to do with the "auth=" 'key'?

Thanks in advance for any suggestions/assistance.

Mike.

In English, the meaning of this error is: Title: Configuration error Content: Failed to read configuration file. Please contact your system administrator.

I had this error for a long time. But it's not too serious. Just hit ok and I can use all the recovery tabs as before without any problems. But every time I open windows and open the browser, this message appears. I feel very uncomfortable and tired without knowing why. Even reinstalling the browser didn't fix the problem, I tried it before and lost my favorite browser theme. And 1 more thing if someone can explain. If it can't read the configuration file, how can I still use the browser? What does that configuration file do?

This message only appears when I have not opened the Firefox browser on my computer. If I already have the tab, I can open another firefox browser without that message appearing. Only when I close all tabs. Open it again and it will appear. And click ok to use normally.
