Forum zgromaźeństwa Firefox

Hi there.

The original problem is described here: https://support.mozilla.org/en-US/questions/1472503 ( Also the solution I found.)

Jaws and James seem to have left the building.

This problem first occurred with the update from V 135.0.1 to V 136.0 . Currently on V 136.0.4, and every update has exhibited the same behavior.

I have the same issue with two laptops, running Windows 10. Each has been through a few update cycles, and the "Restart to Update" always fails.

So, I close FF, watch for the Resource Monitor to quiet down, and reopen FF.

When I go through this sequence, I notice that the screen will flash once VERY quickly before opening the home page.

FF seems to function normally otherwise.

Thanks for being there,

greg moehl

There is a similar (but not identical) topic on Mozilla Connect , and I posted there. But I did not get a response. So I am re-posting on this new topic on Mozilla Support. I have a similar problem to what was discussed on Connect. I am using Firefox 133.0.3 on Windows 10 Professional. After Firefox has been running for a while, I get a message from Windows 10 that the free space on my C:drive is low. I did a directory listing on my C-drive before and after Exiting Firefox; I saw no large files disappearing. Then I decided to do "dir c:\ /ah" to see hidden files. What I saw was that pagefile.sys decreased in size from 29,925,748,736 to 16,270,770,176. This was a decrease of 13.7 Gb. Is this normal? I have lots of windows and tabs open in Firefox. Thanks.

Hi. New issue today. Running FF V 137.0.1. that was updated on 4-8-25. Unable to login to Credit Union online banking. Cleared browser. Nope. Restarted FF. Nope. Restarted computer. Nope. Called Credit Union: They saw no issues with account, suggested trying MS Edge browser. Boo. Hiss. Tried Samsung Android Smart Phone running FF V 136.0. Works fine. Rolled back to a previous restore point that had FF V 137.0 running. Scary stuff. Same login problem. Fired up MS Edge. Works fine logging in to CU account. I see this issue comes up occasionally. Is there a fix in the works? Will it go away AIBM? Thanks for being there. greg

I am no longer given the option of being able to scroll through my open instances of Firefox. When using my primary smaller horizontal monitor, it only shows 28 open instances. When making my larger vertical monitor the primary monitor, I can see 62 open instances (Not Tabs). Either way, the little arrow no longer pops up under the open instances list allowing me to be able to scroll to what instance I want to view.

The sidebar that shows the browsing history is a very convenient tool. However, now, after closing the window, the option is reset to the bookmarks bar. You have to select the browsing history again, which is very inconvenient. Is there any way to fix this?

Anytime I close out Firebox all my tabs and history are gone. Even if I make tabs it keep being deleted. This happen recently after I sync with my steam deck. I didn't touch my setting recently, Firefox should auto-update so it good, and my account is safe. I don't know what is happening that can caused this bug and only thing that I find is weird is having two same account on my deck and not my pc. Only thing I can think to fix is to uninstall Firefox which I will try later.

For the last several days, Firefox has become nearly unusable. It started using an excessive number of processes. Then I started getting very frequent hanging and "Mozilla Firefox (not responding). It may freeze for several minutes, and often I have to shut down and restart my PC. It then takes much longer than usual to shut down, and after restarting, it takes several tries to get Firefox to open. A couple days ago, I updated Firefox to the new version for Windows 7 Vista, and it may have actually gotten worse.

It took me about 25 minutes to type this short description of the problem because it froze several times.

I've never had this issue until a few days ago when there was an update but all of a sudden my tabs constantly rearrange themselves and it's driivng me insane!!! It's never done this until the recent update and I can't figure out how to make it stop! Please help!!

For the last several updates to Firefox I receive the following NSIS Error: Error writing temporary file. Make sure your temp folder is valid. Nearly every time the update completes successfully. My disk is 90% full and perhaps that is the problem although 20 GB remain. I have run disk cleanup to remove files, especially W10 Update files. Clear Disk Info doesn't identify any problem areas (all green).

Any other likely sources of the message? Thoughts?

Why is firefox giving me there errors?

suddenly after a firefox upgrade this afternoon, the contacts lists for gmail started to get reduced in size so small it looked like specks of dust instead of names , adresses, etc.

another pc here which hasn't been upgraded  has no problem.   both pcs have the same 5 GMAIL acccounts, 

but the secondary (also sedentary ) has not been used for 2 or 3 days. Both are laptops, with Win 11 and are upgraded as soon as they available
