For weeks I have been trying to find a solution to getting "Error 15" on certain websites when using Firefox. Opera and Edge have no problems with those sites, only Firefox has problems. I have tried every "fix" that I can find on the Mozilla site and none of them work. Is there anything else I should try before I abandon Firefox? Could it be that Firefox is now unreliable under Win7 Pro 64-bit? If so I will have to abandon it because this computer cannot run Win10 or later.

I have searched the "Knowledge Base" to no avail--no solutions, just others with the same problem. Every day a handful of fresh Trouble Reports pop up on my desktop, even though Firefox is not even running (as verified through the Windows Task Manager). It got so bad, I uninstalled/reinstalled and the problem persists. Otherwise, the browser works fine. My expertise lies outside trying to decipher arcane strings of data buried deep in the bowels of my computer, and frankly I should not have to start hiking up a steep learning curve just to get this to stop. I should add, I have been a fiercely loyal Firefox user since its inception.

I'm not super happy about sharing internal data with the rest of the universe, but have done so anyway in hopes we can get the madness to stop!

Is there anyway to reset your password without losing bookmarks and other personal data? My old computer crashed and I don't want to lose all that data. For some reason, my password isn't working.

For some reason my automatic email signatures in Outlook Live websites (outlook.live.com and owa's) become gibberish (see attached image). I have been having this problem for a while now (aka, not only after the last Firefox update), but it is intermittent.

I have already tried identifying whether the issue is in an extension or in Firefox itself, but without success. Whenever I restart Firefox in Troubleshoot mode, it solves the problem. But disabling all extensions and restarting Firefox does not. Restarting Firefox (not in Troubleshoot mode) sometimes solves the issue, as well as right after an update of the app; but not always. Starting Firefox after a computer restart usually brings the problem back. This problem also happens in my laptop (MacBookPro), so it is not restricted to this computer (macMini).

I would appreciate some help in identifying the culprit, so that I may contact the appropriate support team (if not Mozilla itself).

I recently upgraded from 108.0.2 (64-bit) to 109.01 but it slowed my PC down to the point of uselessness. Nothing else changed application or OS-wise. PC, OS and all Apps are current & up to date. Defrag, Cache Clear a& all similar utilities run on scheduled basis prior to upgrade and everything A-OK.

Is this a Known Issue? If so, is there a fix coming

(1-7-23, Windows 10): My problem for the past month is that FF won't keep me logged into sites where I specifically ask to stay logged in. It remembers my passwords but will not keep me logged in to Amazon, Yahoo, Facebook, etc. This is a home computer only used by me so I don't want to be logged out. Also, I get messages from sites saying there's a login from a new browser and I keep having to confirm it's me. It will work for a day, but when I start the computer on the next day, I'm logged out of everything.

I have done all these things:

• Refreshed FF
• Uninstalled & reinstalled FF
• Cleared the Cache
• Cleared Cookies
• Settings: Remember History
• No checkmark for Private Browsing
• Tried turning off Enhanced Tracking Protection for affected sites
• Tried changing Privacy to Custom, and un-checked Cookies to allow them
• No checkmark for "Delete cookies and site data when Firefox is closed"

I think I have solved the problem after re-starting or completely turning computer off and on again, as long as it's the same day. The next day it's like it's a whole new FF browser. This started a month ago or so. Can anyone help? Nothing I do seems to work. Thanks!

I exported my bookmarks to an HTML file. WHen I try to import them I get an error message that there are no items. However, when I open the file I see the links and when I click on them I am taken to the sites.

Thank you.

entire firefox toolbar enters overflow menu thingy when i watch videos in full screen (player full screen not FF/f11 fullscreen), this also happens even when i reset toolbar to default, all of it still enters overflow, and i have to press F11 twice to get it "out" this is totally new, (didn't even know there was an overflow thingy), in over a decade of firefox never encountered this seen it, to the point i didnt' realize overflow was a thing, and on a new install i can't seemingly to get it to not keep "eating" my toolbar

this is super annoying, and i would really really like a way to "Lock" my toolbar so this doesn't happen, and i can't imagine it's normal in anyway, specially when it happens on default and a clean install/empty browser, please help get back to normal toolbar "sticky"

I just installed Firefox on a new Windows 11 desktop computer. I ported my profiles over and it appears everything came over EXCEPT: - Themes aren't working. I've tried switching them and they still don't display. The menu bar is black w/white letters; the toolbar is gray with white icons/letters. - My extension icons are there...sort of. If I hover over them I can see the tool tip but the icon doesn't appear on the toolbar which is light gray in color. I can live without the themes if I have to. Not so much the invisible extension icons. Any suggestions as to how I can get them to appear as they do on my Windows 10 desktop? Screen cap below. Cursor is hovered over the Undo Close Tab extension icon but where's the icon? Any suggestions as to how to troubleshoot this will be appreciated!!

Hi, I recently began having trouble getting Youtube to work on Firefox.. Doesn't seem to want to connect, slow to open, mostly not at all, sometimes loads half the page....etc Constantly comes back with a message that I am not connected to the internet, which is nonsense.. It loads instantly in Microsoft Edge..which I normally don't use at all. I have deleted all history , Cache etc multiple times and that works maybe for one time and then the problem is back again.

Appreciate some help.

Hi, I explained in the query itself. I do not have any add on or downloaded any ad blocker software. But genuine sites are not allowed to for eg. to access a speed test website keralatelecom.info. I get this alert

Hello,

A few weeks ago something changed in my Firefox browser where popup boxes do not show. For example, if I want to download a file, the pop-up box with the options for downloading do not show. If I want to attach or upload a file, the popup does not show. Even if I want to change a setting in my my Firefox account, I cannot if it requires a popup box.

If I restart my computer (not the browser), the problem goes away, but eventually it happens again.

It is really disruptive. Now I have to do about 60% of my work in another browser. All of my account info, bookmarks, and passwords are saved with my Firefox account, so I would prefer to be able to use Firefox. Any suggestions on how to fix? I should also not--this has persisted despite updating.

Hi, for the last week or so I've noticed an irritating translucent banner at the bottom of certain web pages. I have refreshed Firefox and cleared the cache, but to no avail. Please see attached image. This is from https://www.majstro.com/

It starts and ends a distance from the left and right edges of the page. I'd love to rid of this.

Hello Mozilla Volunteers,

I'm having more issues with Firefox running website, such as compared to Chrome, and now I can't get past this error playing videos on the surfing website Surfline "This video cannot be played because of a technical error.(Error Code: 100000)" Any suggestions on how to remedy this would be appreciate.

Thx, Colin

Hi! I have a brand new installation of Firefox and it is crashing when I try to share my screen. It crashes in troubleshoot mode too. Any ideas about how to solve it? Thanks!

The Subject says it. I have this line "Your browser is being managed by your organization." in Config under Sync. I am a private user so there is no organization. I want to get rid of this.

I'm trying to troubleshoot why Google Chat will not sound an audible alert while Google Mail does. I can't find any settings that would affect this so naturally I suspect this organization line.

I'm using the Mozilla .deb and not the Ubuntu snap.

Thanks, John

Trying to login to www.visualmicro.com forum site. It has been a while since I've used the site. Now I'm getting Secure connection Failed - PR_CONNECT_RESET_ERROR page. I've contacted them and their reply was "The issue you have with the forum is related to something on your pc. The forum is actively used by many users." I've gone through the troubleshooting procedures to no avail. Please advise.

Hello,

I am experiencing an issue when accessing my website using Firefox on Mac.

The browser blocks the loading of an external Google Adsense script, logging the following error: "Content Security Policy: The page's settings blocked the loading of a resource". Here is an example URL:

https://www.varbes.com/

To my understanding, the site does not have a Content Security Policy ('CSP'). We don't send a CSP network header or in the HTML, so am at a bit of a loss as to how I debug this.

I don't see the same issue using Firefox on Windows, or with Chrome, Edge or Safari. I have performed a fresh install of Firefox on my Mac to make sure no extensions are causing the issue.

Other websites seem to be running the same AdSense code okay.

Any suggestions would be greatly appreciated.

Many thanks, Matt

I can't delete certificate authentication solutions In the "certificate management" section, I see the "authentication solutions" tab for secure sites, but I accidentally selected the wrong certificate, and now I can't change it. The list is displayed only in the viewing mode, it is impossible to delete or change the solution. What can I do without deleting my profile? Use last version 108.0.2 (x64)
