Firefox Community Forum

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.

Since the last update that I received from you and installed I can not longer get in to my online Bank account. I get a window telling me access is denied. I am unauthorized to access this resource. with a Reference ID of e727ec65b1 Troubleshooting steps 1. Reload the home page and try again Failed 2. Clear your browser cache and try again. Failed 3. Try logging in with a different browser. No they aren't as secure 4. Try logging in with a different device. No only use my desk top for business.

The Bank says they are having trouble with Firefox. I don't want to have to use Edge or Google they aren't as secure as Firefox. Please fix this with the Horizon Bank. Thank you. dleeb17

This is a weird one and I'm hoping there's a reassuring explanation.

I had Firefox and Sumatra PDF open, nothing else on Win 10.

I switched from Sumatra to Firefox (1 tab open), searched for something, and Firefox froze, and after a while Windows gave me an option to terminate the non-responsive program, which I did, and Firefox closed.

But the hard disk was active 100% afterwards, and everything slowed to a crawl, and I couldn't even get the Task Manager to open, so I did what I haven't done in many ages, killed the power. (Experience tells me a memory leak.)

After the restart Firefox opened, a bit slowly, to the last open tab. Browsed a bit. All is fine. Closed Firefox, opened it again, and now I'm logged out of every website, including the saved preferences, e.g. of Wikipedia.

It's worth pointing out that I closed Sumatra just fine, but it too lost the history (it remembers which page I last viewed for the opened documents).

Since Firefox was the one to freeze, and to work fine afterwards, logged in and all, then lose all after opening it again, I'm not sure what happened, and if there's anything I can do.

Sorry for the lengthy post, but basically:

Is that expected after a freeze/recovery?

I cannot get supporrt.mozilla.org pages into dark mode. My eyes are not good and I can barely read these pages. I have Dark Reader enabled, but I cannot find any way to enforce dark mode. Is it possiblle and, if so, how do I do it, please?

Regards,

Bob

this page "247sports2.com" keeps popping up when I log in to my account on "247sport.com! and I cannot get past it. Is there anything I can do?

I have tried everything to get back to a white background on Yahoo and Google while I'm using Firefox on this HP laptop, and have been unsuccessful. Every time I open Yahoo or Google, it starts out with the white background, but instantly changes to black. I went through all the settings I could find, and nothing helps. I even copied my Firefox settings from a different laptop on which I do have the white background, but no luck. Thanks in advance for helping.

I've been struggling with Firefox's poor performance on my aging computers. I have a new macbook as well as 2 vintage macbooks and my desktop runs OS 10.13.6. Performance after the last several updates is slow and occasionally websites not showing, which caused me to attempt to downgrade to FF 78.6, but tried clearing cache instead. I had way too many websites open. Clearing cache improved things slightly, but now this—Pocket: after resetting Firefox I'm confronted with the poor decision-making that has allowed your browser to be infiltrated by 'Pocket;' news for the somnambulist slumbering through the Trumpocolypse to grease our slide into full-blown fascism. Do I exaggerate? Yesterday Trump called on the justice dept to open an investigation into the Republican in his last administration who declared the 2020 election results valid-- So, by extension, we now live in a time when the king, er, I mean the Commander in Chief, uh, president, whatever, can use the government to target anyone he doesn't like for any reason. Newsworthy? Okay, amongst the twenty or so Pocket offerings is a ProPublica story and one from AP I'd find interesting, but I'd have bailed long before I saw them because of all the 'amazing' credit card offers and such BS in the way. Which is too bad, because that means the Mozilla effort to reign in AI comes last of all. Open source, with ads.

Now there is no "other" category for topic of question. This concerns display, layout, and functionality.

Having a huge problem with Firefox recently. It looks and behaves like Microsoft type display, security, and function all around has been superimposed on Firefox. Every time I need to do something online my effort is first redirected to trying to fix configuration problem on Firefox.

It is bad enough to have to do battle with windows 11 to config the layout and display so that it is functional instead of going from one screen to another and another when there is an issues that needs configuring, which always then requires a search and fixing it in Microsoft registry (if possible). Now that is happening with the Firefox display, layout, and functionality which requires a search try to find a page where some kind soul has provided a fix for FF via about:config (if possible).

My brower updated to 136.xx in mid-march after I had already disabled auto update. However, have not had problems until recently, so it seems to be something the microsoft system has started doing to compromise the configured functionality of Firefox. It is no impossible to update or change passwords because "microsoft security" has taken over. Did Microsoft buy controlling interest in Firefox, or what.

Today The layout has started being a problem too. Very elementary without features, with huge words and images although I have changed nothing in Firefox. It is as dumbed down and tedious as Windows 10 when it was brand new. I use a desktop and I really don't want it to look and behave with the limits, and appearnace of a large sized mobile phone screen.

No Firefox update since mid March is showing, however something is interferring with the Firefox display, layout, and functionality. I can only guess it is the Windows 11 OS . . .

Is there a way to protect Firefox from Microsoft meddling with the Firefox configuration?

I have not yet tried to stop enhanced security in each website that is a problem (though most of them currently are, not simply individual websites). Perhaps that is the problem . . . at this problem it needs to be universally disabled if that IS the problem. All the additional security being piled on is simply hoops to jump through for users. We all know it does not stop the pros who are intent on hacking as a team sport. I really do not want to have to fool around signing to a Firefox account, and getting a code to be able to complete the signin to be able configure the brower to simply access the internet.

Starting to think FF, including support, is being managed and responded to by A.I. - which always ends up being a programmer problem that creates the limits. Intentional or not is the question.,,,,

Hoping some kind souls have found solutions, or locations to solutions they are willing to share.

Thanks - from redirected and disenchanted in ABQ

Continuously being logged out of Mozilla on Firefox on different PCs (same account). Mozilla will not accept already saved password. I keep getting prompted to change password. I "change" it to the original password. That usually (but not always) works. How to fix?

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.

I have tried the sidebar and it seems OK BUT the background colour is pale blue and the text on top of it is white. This means it is very difficult to read. How do you change either the background colour of the sidebar OR the colour of the text in the sidebar? I have tried the main settings (Manage Colours) for Firefox and found nothing.
