I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

Using 2025-04 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5055612) Firefox 138.0.1 (64-bit) and says it is up todate. I have looked at the about:config to find the browser.tabs.remote.autostart but it does not exist in the list of processes. I have also unchecked in settings both performance options intermitently to try and correct this problem, but nothing happens: (unchecked) Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. (Unchecked) Use hardware acceleration when available Nothing pops up to allow choosing a different number as many support articles say. I have AdBlocker running as an add on and turned off the duck duck go privacy essentials and still nothing stops these insane amount of processes clogging up my computer. right now, on this page there is only this tab open and there are 13 processes running. Please send real fix instructions- thank you

I'm trying to access my https://mypay.dfas.mil account, but, though previously all was well, now an error message tells me that you "can't connect to the server".

I have a network connection, but apparently Firefox may no longer have "permission to access to the web". I'm sure this is wrong because I can still access pretty much everything in the normal way, including other government sites, such as Social Security, using the Login.gov portal, though mypay is not listed as 'connected.'

What happened, and how do I fix it? Also, the error message says that I should "Check that Firefox has permission". How do I do that?

I use FF on desktop. Recently, I've run into a problem. My desktop browser will not load any pages... except Youtube. Youtube loads just fine, I can open a video or browse channels or community pages normally. I have fully reset my browser, reinstalled it, and disabled extensions. Other browsers on my PC will work normally. I have very few extensions: Sponsorblock for Youtube, uBlock Origin, and Facebook Container, that's it. I am not using a proxy or VPN. Troubleshoot mode did not fix the issue. I'm not the most tech savvy, so I apologize if I missed anything here.

Any insight is appreciated. Thanks!

I have Firefox on two Windows computers and was wondering what is the proper way to sync them.

One computer is not used often and I want to sync Firefox on it it with the Firefox on the computer I use daily so I want the Firefox that does not have the updated files updated using the Firefox data files on the computer I use daily and not the other way around. So what is the correct procedure to do this other than to make sure the Firefox program version is updated on the computer that is not used often?

Thanks

When I try to compose a new email, or reply to one, the pane opens to compose the email, but immediately closes before I can enter anything, reverting back to the Inbox. A new, empty draft gets created. But there is no way I can create a new email. Problem does not occur on other browsers. If I open a "New Private Window" and sign in to Outlook, I can then create the email there, but after a while the same problem occurs in that window too. Tried clearing Firefox cache temp files and cookies, but that did not resolve the problem. Using web based Outlook, Windows 10. Firefox is up to date.

Any suggestions?

So I just noticed after downloading the new update to Firefox, version 139.0.1 that something new came up in my task manager called Crashhelper. Never seen this before. Closed it down and it seemed to have no issues shutting down at least. I haven't had Firefox crash in recent months, so I'm assuming that this cropping up might be a glitch of some kind? I looked this up to see if anyone else had this issue, and it seems someone on Reddit did encounter this, on Linux, and another on Windows also seems to have run into it. How do we stop this from coming up whenever we start up the browser?

I accidentally uninstalled firefox and need to recover passwords and bookmarks. Can this be done? I run an old dell latitude with Windows 10 and was trying to cleanup apps running in background at startup since it was running very slowly. At one point I saw 2 firefox icons. Uninstalled one and lost everything. Can you help me. Michael Evans

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

places.sqlite: this file records EVERY website I've ever visited in a db table! This despite opting out of History and flushing daily It's frustrating that FF surreptiously collects such personal info. Why record every site I visit, date-timestamps, frequency, etc.?

moz_historyvisits_dateindex ON moz_historyvisits (visit_date) moz_places_lastvisitdateindex

As test, I changed the name to places-sqlite.old to see if FF will create a new one It didn't make a new table; re-created the old one.

I need to update FF because of the expired certificates, but would like to clear these out first. Similarly, can I get rid of the icon database? My bookmarks are backed up as JSON and HTML files. I just wished they didn't contain extraneous info

I understand that as from 14th March 2025 I will need to update Firefox. I am currently running 102.0 and have sucessfully prevented Firefox from updating to later versions. I did this to prevent the updates positioning the tabs in the wrong place. Please can you tell me if the CSS script that I use to put them back into their correct position, i.e. below the Bookmarks Toolbar, will still work.

Also, will newer versions allow the user to choose where the tabs are positioned? It was possible to do this in earlier versions and the choice is also available in other browsers.

I have also managed to stop Windows 10 updating for several years too, Microsoft kept altering my laptop in unacceptable ways.

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

I cannot access my Coventry Building Society account online using Firefox. The building society says it is is due to a recent Firefox update being insecure. Can Firefox fix this?!

When attempting to drag/Insert picture into email text, the message "The following files couldn't be attached: filename.jpg. Please try again later." appears. I have not been able to find a solution. The dragged/Inserted picture always ends up outside the email text box and cannot be moved into it. What is a solution?

Is this something new or do I need to reload Firefox? Firefox 133.03 64-bit is up to date on Windows 10.

It worked last Christmas!!! It is not important now that the holiday is over but would like to fix it.

Within the last week, my homepage has changed in look and operation. It no longer has all of my bookmarks, I can no longer navigate back to my homepage from other sites, etc. Also, it have a very plain, sterile display. What changed and how to I get back to my original homepage?

You have invited me to download a new version of Firefox.

So What do I do with my existing Firefox?

If I don't like it, can I go back?

Please let me know.

I always use the middle mouse button (pressing the scroll wheel) to open and close new tabs, but since the update, it doesn't work anymore and now types "=" if the cursor is in a text field. For context, I use an MX Master S3, mapped with Logi Options+.

Anyone else having this issue? How do I roll back to the previous version??

SOLVED: It was a bug with Logi Options+, not Firefox. When I hovered over the tab for the presets I had for CaptureOne, I noticed it also said Firefox. So seems something weird happened there. Deleted that preset and the issue in Firefox went away.

I couldn't find a way to delete this thread, though.

The icons on my home page suddenly became significantly reduced in size. Sure, I can tell what they are, and I've increased the text size for their identifiers below the icons. But they are now so small as to be not pleasing to the eye. How can I put them back the way they wuz?
