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 have been receiving several similar emails that disrupt my email use. How do I remove from my computer? Here's an example: An error occurred during a connection to 6yv5qzb7f8.boats. SSL received a record that exceeded the maximum permissible length.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG

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

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?

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?

Chrome user returning to Firefox here; I'm experiencing an issue where most pages would take at least 4 to 6 seconds to load, especially for heavy media sites like YouTube which could take 6 seconds for it to be barely usable, and 10 or 13 seconds for it to finish loading. My internet speed is 1gb at most and 800 Mbps at the least.

It loads sites like Reddit pretty fast, like 3-5 seconds interestingly. It's largely YouTube and other sites where the pages load infuriatingly slowly, and Chrome Mask did not helped with this.

Here are the things I did: Refreshed Firefox, started in Troubleshoot mode, installed Chrome Mask for YouTube (Did not work), disabled DNS, closed all foreground apps except Firefox, used a different profile and enabled/disabled hardware acceleration.

Specs: CPU: i5-3570k GPU: GTX 1070 Ti RAM: 16gb DDR3 OS: Windows 10 Hard Drive type: SSD

Final notes, it says I use Microsoft Defender Antivirus but I am actually using Malwarebytes. I also use uBlock Origin which is the entire reason why I permanently switched from Chrome to Firefox.

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

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

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.

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?

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?!

I was planning to start using the AI chatbot sidebar finally, tried out all of the free options available and settled on HuggingChat. The very next day, HuggingChat ceased operations. I don't really like the other preset options, but I have a couple of other models that I would be interested in trying out. Is there some way to add a different model than the five preset or am I just out of luck?

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.

Hello to those of you reading this,

Over the last five or so days, my Firefox has been acting in a wholly unpredictable way. Every time I launch Firefox, the inspect element tab will open and close itself repeatedly for about 3-10 seconds, stop for a bit, and then start again. CPU usage by Firefox skyrockets whenever the glitch occurs.

I have tried Troubleshoot mode, I have tried a clean install, I have tried to refresh Firefox, all to no avail. This doesn't seem to have anything to do with a Firefox update, as the last update to my Firefox was well over a week prior to the start of this issue.

I am running several extensions: uMatrix uBlock DuckDuckGo Privacy Essentials DecentralEyes PrivacyBadger BetterTTV Facebook Container Firefox Multi-Account Containers TTV Ad-block Wikipedia Context Menu Search Redirect AMP to HTML

However, none of these seem to be the cause of this issue as it persists in Troubleshoot mode and after a Firefox Refresh.

The only reasonable lead I have regarding this issue is that the browser console spams the error messages as can be seen in the image attached to this post. A recurring element is "server0.conn0.watcher2.process16". I'm afraid I know only enough about coding to understand that this is probably the root of the issue, but am completely lost on how to fix it.

Another tidbit of information, whose relevance I doubt but am including nonetheless, is that I recently transferred my C:/ drive from an SSD to an NVMe. I'm wondering if perhaps the application is trying to call on a process stored on the other drive. I find this unlikely, as similarly to the point on the Firefox version this only started occurring a week or two after I transferred the drive over.

Any assistance on this matter would be greatly appreciated!

(This is copied nearly directly from a post on r/firefox made a few hours ago—I decided it was best to spread it here for more exposure. The only change was the removal of the add-on names from the title due to character limits; these are Form History Control and Text Area Cache.)

I hope the title explains what I am looking for well. My main computer has had... spooky behavior with its file system recently, and I have been recommended to make a back-up, format my drive, and re-install my operating system (possibly upgrading from Windows 10 to 11 in the process). The biggest hold-up to me doing so is this, as I have no idea how to transfer the extension data between installs, or convert it into a human-readable form. The sheer number of writing drafts in those extensions both make losing them an unacceptable situation and copying the data manually into a document entirely impractical. So, can anyone help me with this? For context, I was on Firefox 138.0 when I stopped using my main computer due to those issues. (Note: It will certainly last long enough to do the Firefox Syncing and other back-up operations, just not for many more weeks or months.)
