I will open a few tabs, then close some then open more , then everything slows down, I go to task manager and see that many tasks are still open under Firefox

I want tabs to close ( end process) when I close them

So now I manually 'end process' and the machine resumes speed

How do I get firefox to End Process when tabs are closed

this is w 8.1, don't know what version of firefox, pretty recent

this is firefox mozilla, as best I understand, not that I know why these two are always paired

About two days ago the cursor started disappearing / flashing when browsing in Firefox. It does not mater where the cursor is placed on the screen either the arrow or the hand will flash when moving. My system is a windows pro 10 system with all updates, last updates for W10 were made a couple of weeks ago, on Firefox whenever it asks to upgrade I do it.

Specifically: 1. If the mouse is stationary there is no cursor, if I move it the cursor flashes. 2. When the system comes up and I launch Firefox all is OK for about 2 – 3 minutes then the flashing begins. 3. If I stop Firefox ie “X” it and restart it the flashing occurs within 0 – 30 seconds. 4. If I restart the PC steps 2 & 3 repeat.

I have two other PC’s Windows Home, and Windows 7, as well as a laptop with Windows Home all with Firefox 101.0.1 all up to date all do not have the above issue. This does not occur with any other programs. I have two monitors, tried Firefox on each makes no difference same problem.

I have tried searching the internet and all I find is about Caret which is off. I uninstalled Firefox and installed it. That made no difference.

Any assistance will be appreciated.

Thank You

Hi.. when i browse to https://www.youtube.com/, the page didn't load.. it's say error "Did Not Connect: Potential Security Issue". Error code: SEC_ERROR_UNKNOWN_ISSUER

How to fix it? My firefox was latest updates. Thx

The latest update for Wondows 10 prevents Firefox (and Edge) from loading. Everything works fine once I've uninstalled the latest update so the problem is clearly theirs. I can't be the only person experiencing this problem but contacting Microsoft is next to impossible. I wonder if you can: 1) alert them to this issue; and 2) pressure them to fix it as constantly uninstalling the updates is a pain!

Good morning,

I'm reaching out to see if I can get some assistance with Firefox on of our network. I'm System Admin at Goodfellow AFB. I've tried searching this issues on the web and found similar issues but solutions that were recommend online have not worked for us. Yes I have uninstalled Firefox completely and installed it from scratch. I know it has something to do with autoconfig file but not sure what exactly I'm looking for. Thanks.

Every time I run browser it messages me that downloaded file contains a virus or malware, even I deleted the file long time ago. I tried Ctrl+J "Remove from history", "Clear downloads" and Organize/Delete that entry - Nothing helps. Its deleting, but when I run Firefox its appears again and again. This bug is terrible annoying, please fix it.

Firefox version: 102.0 (64-bit) System: Windows 10 21H2

I recently downloaded a file that may have had some sort of virus or malware. The file came up negative in Windows Defender and Malwarebytes but I deleted it anyways; however, I still get a download popup every time I open Firefox telling me that "This file contains a virus or malware." I've cleared the download library and browser history (cookies, cache, etc.) but I still get the popup from the Firefox.

Is there any known fix for this? Thanks!

Solutions tried but unsuccessful: 1. Checked page size. It is correct at (80 x 297mm) 2. Cleared browsing history, cache, site settings, etc from start of time. 3. I have put print_resolution to 0 in about:config 4. I have put scaling to 1 in about:config ([https://support.mozilla.org/en-US/que.../1297631]) 5. I have put shrink to true in about:config ([https://support.mozilla.org/en-US/que.../1297631]) 6. I have alternated values (1 and 9) of paper_data in about:config (https://support.mozilla.org/en-US/questions/1297631) 7. Uninstalled ticket printer driver, rebooted PC and then installed again (Xprinter XP-80C). 8. Uninstalled Firefox completely, rebooted PC and downloaded again from Firefox website. 9. I have tested on a Laser A4 printer from Firefox on that same PC. Works fine. 10. Attached is the scanned picture of print from Firefox 100. Firefox 100 11. Another attached contains the scanned picture of print (correct one!) when I re-installed Firefox 64 link text

I'm running Firefox Dev edition and I cannot get it to load any pages except for Mozilla pages. I have tried all the fixes suggested there and it still refuses to connect. I'm at my wits end. Any hail mary optoins or do I have to reinstall and start again?

Hello, I have a problem with firefox and it's recently unable to open Google and Youtube due to HTTP Strict Transport Security (HSTS) with an error Code : SEC_ERROR_UNKNOWN_ISSUER

I have done the steps in here : https://support.mozilla.org/en-US/kb/error-codes-secure-websites I don't have any third-party Antivirus

I have also do about:config security.enterprise_roots.enabled by changing to true. It works but unfortunately youtube is broken when i set it to true.

I can't also accept the risk and continue since there's no button that says it.

Thank you

Mozilla Firefox keeps crashing, mostly at startup and if I do manage to get it running it crashes after a while. Doesn't respond anymore, and even the crash reporter crashes. I have tried the following things:

Clean up FF Reinstall and refresh (last attempt included deleting the entire Mozilla folder in Program Files) several times Updated Windows Restarted laptop after every reinstall attempt

It won't open in troubleshoot mode.

I am running Windows 10 on a Lenovo Thinkpad 540 laptop.

Additionally, neither Chrome nor Edge will let me access the Mozilla.org website. I downloaded the custom installer on my phone and uploaded it in Mydrive to get in onto my laptop.

Funny detail: I am in Belgium. I was in Ireland for a week last week and it didn't happen once. Got back home and trouble was back.

My husband is having the same issues, by the way.

Any input would be greatly appreciated.

I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

I cannot seem to reach https://community.esri.com/ via Firefox but can reach it fine with Chrome and Edge.

Firefox says "The page isn’t redirecting properly. An error occurred during a connection to community.esri.com. This problem can sometimes be caused by disabling or refusing to accept cookies."

So I even added the page to list of Exceptions, but still cannot reach site.

Hey, Twitch dosnt work for me (error #4000) and neither do Reddit videos. Pictures and Youtube works and I could not find a solution online. Thank you for providing this awsome browser. please keep fighting for privacy.

I get the above message when I try to view online digital histology slides (website link below). This only happens on Mozilla; when I try it with Safari or Chrome it works fine. Is there a setting I can change to fix this?

Dear Admin,

My firefox browser can't shown the correct myanmar unicode script when I type in google page and other websites also shown the wrongly font scripts that are unable to read. I'd asked to google and they said it is the font rendering problem and advice ask to your team for help. Please take a look and advice me how to fix it. I'd installed myanmar unicode font in browser and set as default. Other websites which are use Myanmar unicode are also shown the wrong script in firefox browser. The browser version is 103.0.1(64bit).

Thanks for your kind response, Htet Aung

When I open Firefox after starting my computer, all of my tabs from the previous session are automatically restored, and they take several minutes to load. I don't have the "Open previous windows and tabs" setting enabled. Is there a way to stop Firefox from loading these tabs each time I open the browser?

I'm using Firefox 103 on KDE neon 5.25.

Using Windows 11. I'm using a free Proton VPN. My Firefox version is 103.02. I want to be able to continue to use the VPN when using Firefox to check my gmail accounts. If I disconnect the VPN, Firefox lets me access my mail site without a problem. When I use the VPN connected, I'm getting a PR_END_OF_FILE_ERROR

Is there a way to keep the VPN on and connect with no error? Is there a Firefox setting I can change? I don't have proxy selected in Win 11 connections. Cache is cleared.
