Firefox supportforum

Our organization recently upgraded everyone from standard Firefox to Firefox ESR 115

Several users continually get the following error:

XUL Runner

"This profile was last used with a newer version of this application. Please create a new profile.

Users are getting the error even after a new profile has been created.

We have tried uninstalling Firefox both through the Control Panel and using IO Bit uninstaller but the issue persists.

All users are running Windows 10 22H2 64 Bit

Copy & Paste not working in Whatsapp Web page. I've cleared cache, rebooted etc. Copy & Paste works perfectly in Edge browser to its certainly a Firefox problem.

I think Firefox updated on my laptop in the last day or two.

I never had a problem with Google Calendar not populating with my calendar info, but today I find that Google Calendar opens, but doesn't fill will data. Calendar still works fine in other browsers, so it seems to be a Firefox issue. What is the solution?

Other Google apps that I use still work okay in Firefox.

I now have 115.0.3 and this problem still exists. It was reported right after 115.0.1 was released. When watching FreeVee on a Windows 10 desktop it stops a short while after an ad plays. It looks like it loses the ability to stream the main movie while streaming the ad. After the ad it plays about 20 seconds of the movie, probably what was in the buffer before the ad started, and then it freezes. I get the circle wait icon, like what typically happens when the Wifi goes down. After a while a message appears saying the Internet is not working. See attached image. Then I get the message (see other attached file) saying Video Unavailable. We're experiencing a problem playing this video. For assistance, please go to www.amazon.com/videohelp. Close Player.

Our IT specialist at UW-Madison is stumped and suggested I reach out to Firefox. He was helping me troubleshoot why Firefox keeps saying it's sending a code to verify my account, but I never receive the code. He has added the "accounts" email to my contacts and I don't know what else to do or try. Any ideas from the community? I need my bookmarks after upgrading to Windows 11 and can't imagine trying to recreate them all.

I have set Firefox as my default homepage and browser, however whenever I do a search or try to go to a website, Firefox starts to load it and then the screen flickers for a millisecond and then Bing takes over - Firefox no longer appears and the Bing logo is in the upper left hand corner. How do I stop Bing from taking over?

Been using firefox for 10 years to access xfinity/comcast email and suddenly can't do it. Keep getting error message "An error occurred during a connection to oauth.xfinity.com PR_CONNECT_RESET_ERROR". I've switched to Microsoft Edge for the time being but would appreciate getting back to Firefox if possible. Any help would be appreciated.

Running Firefox on MacOS. Browser will occasionally delete previous session when re-opening the browser. I do NOT have the browser set to clear history on closing. I have noticed that two of the incidents occurred when I accidentally closed the default window that opened when restarting the browser but I still had Firefox open.

Really frustrating when I lose all my open tabs with research I was conducting for work.

I've been using firefox for last 15 years now to do my online banking with RBC. As of 2 weeks ago it has failed to open online banking on the RBC website. Google chrome however works. When speaking to RBC customer support they say it is a problem with firefox and will likely go away once firefox updates to a newer version.

Hope you can help with this issue since my browser of choice is firefox. Thanks

Suddenly i keep getting this error code. After trying things like refreshing Firefox, using No Proxy option and still getting this error. I dont know what to do, except for changing the browser.

Received this message thismorning while using my Ledger device:-

Something went wrong-U2F browser support is needed for Ledger. Please use Chrome, Opera or Firefox with a U2F extension. Also make sure you're on a HTTPS connection.

Had this issue in Firefox, uninstalled it from my Mac and downloaded a new copy, same issue persisted. Moved to Firefox Nightly, same issue. I'll be working on something and then my tab will crash, showing the Mozilla "your tab has crashed" window. Any new tabs I open will display this as well, automatically crashing. Sometimes restoring them works, sometimes it doesn't. This will also crash tabs in other windows, as well as new tabs opened there. I've tried completely removing both apps and reinstalling them, but the issue persists. I have a video but this forum doesn't seem to have video uploads--would be happy to email Mozilla support to get this looked at if that would be helpful. I loved this browser, I'd like a solution so that I don't have to find another one! Any help appreciated.

Additionally there seem to be two copies of the app operating simultaneously, they both appear in my dock at the same time? Image attached.

When i open a picture from a page, and want to save it on my computer, I right click on the picture to save it. At that very same second, Firefox freeze and I need to open the activity manager to close it.

What also confuse me there, when I find Firefox, there is a number behind the name, like: Firefox(7) Does it mean that 7 Firefox is opened in the background?

What is the problem?

To save a picture now, I need to use Edge.

Hi everyone I have a question I have used Firefox as my default browser for many years. This mourning I started getting “Secure Connection Failed An error occurred during a connection to www.youtube.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.” When I tried to go to any site other than the homepage. I find it very suspicious I can only use Bing to get on the web. Anyone know what is going on.

In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.

When searching queries, this error will come up; however, when searching full length URLs it works and sends me directly to the website. I've looked through the Q/As and they all recommend clearing cache/cookies and messing with the history settings to resolve the problem. However, after doing all that and messing with other settings I cannot seem to understand why this started to happen.

When in private browsing mode it works fine and I can ask whatever and I receive all the possible websites to click on. It's just on normal browsing that I receive the error message. Am I going to need to just uninstall Firefox and reinstall to fix this? Or maybe there's something else I can try out. Thanks!
