Since the start of Firefox Quantum release, when I returned to Firefox I've had issues with Firefox closing itself randomly on page loads - sometimes it can happen right after I start browser, sometimes once a day, completely random, haven't noticed any patterns.

I've tried to google and look into this forums, I've seen people reporting similar issues (but not lately) and I've tried various fixes suggested here and there, for example:

- Disabling all extensions

- Disabling Hardware Acceleration

- Reseting my profile

- Reinstalling Firefox

- Heck I've even reinstalled my Windows


Not once has the closing triggered crash report.

I don't have any similar issues with any other software on my computer so it must be something Firefox specific. I've monitored my PC resource usage, thought maybe somehow it hogs up all my CPU, RAM or disk and that makes it close - nope, same haeppens even when CPU usage is 20%, RAM 12 of 32GB, disk 0-5% (SSDs) etc.

Honestly I'm out of ideas what to try and if we somebody can't help me find a solution I sadly may have to abandon Firefox once again (which I really would not like to do)

Last night I did the new firefox update and every since then I have been getting the following error on multiple sites. Including Tumblr, Google, yahoo mail, and many others.

"Network Protocol Error

Firefox has experienced a network protocol violation that cannot be repaired.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem."

I have tried searching out the answer on here and most said to just clear out the cache which is what I did and I am still receiving the error at random times on different sites. I can refresh and the site will load but then if I got to another page of the same website or a different site the error will just appear again. Thanks in advance!

FF 65.0 (64-bit), Windows 10 1803

i have been using Firefox for several years now in the office to access my Exchange management console. i have several add-ons loaded. the other day, Firefox just stopped working and won't allow me to access my Exchange management console website. i started troubleshooting by removing all add-ons and that worked. but as i enabled the remaining add-ons, again Firefox won't allow me to access my Exchange management console. no matter in what order i re-enable my add-ons. now it has come to the point where i have no add-ons and still won't allow me to access my Exchange management console!

i have at home same Firefox with same add-ons all enabled and i am able to access my management console from the Internet. our SSL certificate is still new from Comodo.

the subject is the error. how does one fix this?

Firefox Quantum 65.0; Windows 10 Pro; Grammarly, OneTab, RES, uBlock Origin

since about a week ago firefox always saves the open tabs and opens them after restarting the browser. It happens automatically and I can't stop firefox from doing so. I want every tab to be closed when I shut down firefox and they shouldn't automatically be reopened.

The box for Session Restore is unchecked and in about:config browser.sessionstore.max_resumed_crashes is set to zero and firefox still automatically restores the sessions

I was trying to activate Crackle on my Roku box by going to crackle.com. The connection works but I just get a brief screen with three dots followed by a blank screen. However, I have no such problem in Chrome; if I go to crackle.com/activate I get a screen that allows me to enter an activation code. I've deactivated both Noscript and Adblock but it makes no difference. Although I solved my problem by activating via Chrome, I'd still like to know why the website crackle.com is inaccessible in Firefox.

For some reason, when I started my computer this morning the tabs were all bright blue. When I click on another window and change focus, it reverts to the light gray that it should be, however going back resumes the problem. Starting in safe mode does not help, and turning off hardware acceleration does not help. I have restarted both the browser and my computer, and the problem resumes. The only thing that seems to change it, is when I change it to certain themes like space, who completely change the color of it. The default, dark, and light themes all are affected by this bright blue tab bar.

I was suddenly getting prompts to update Flash Player. This hadn't happened in months, so I hadn't updated Flash Player in a good while. The first time, I ignored the warning prompt and activated Flash anyway and played the video. This was from tcm.com (Turner Classic Movies). The second time, I decided I'd better update Flash Player, and did so. But now the video wouldn't play at all. There was a locked box icon. I searched on various fixes, looked at a few Mozilla support pages, did a plug-in change starting from the sandwich icon at upper right, same thing. Found another fix idea. Went into the C drive, navigated eventually in Windows to the Macromed and Flash folders, and deleted NPSWF32_9_0_0_169.dll. The red locked box went away. A video played. Next time out, though, back to nothing. In IE, the link will play.

I have had problems with Firefox Sync for a while.

I often reinstall operating systems I use. After each reinstall, I try to sync to my account. I get denied. The email gets returned.

I have bypassed this problem a number of times. I am not sure about the exact solution, but either waiting for 24 hours since last attempt to login or fiddling with Firefox Sync settings through my phone which is already logged in seemed to have helped.

Fiddling with phone settings does not work anymore. It may have never worked. I have not waited 24 hours since last attempt to login as well, so that could be the fix I am looking for. However, the main problem I have, is that I cannot bypass it in any other way. I am able to login to Firefox Screenshots for example with my account, but I cannot sign in to my Firefox account itself. It is not a good user experience.

I understand that this might be used for my own sake, to protect my account from potential intruders...however, I am very dissatisfied with not being able to sign it to my account for over couple of days because of such restrictions.

I do not think anyone can do anything about this, it will probably require redesigning existing safety measures just to deal with this obscure problem. I will wait for 24 hours and will update this post after I get the result. Maybe I can help someone else who is on the same boat as I am. I could not see similar problem on the internet other than a few, of which did not portray the problem in a way that I found relatable.

But maybe there is another way unbeknownst to me.

Either way, thank you for reading. I hope you have a nice day.

I have used Citibank Virtual Credit Card numbers with Firefox successfully for years. When I recently updated to Firefox 65.0 I ran into a big problem. The pop up window appears, the flash wheel begins to spin, then the page appears to be just a blank.

I can still access the VAN with Internet Explorer 11.0.x I have downloaded the Citibank dedicated VAN program and that works fine too. I am using Windows 7 Pro 64 bit.

I have already tried turning off all of the security settings, cleared cache, rebooted, and tried logging in again.

There is just something preventing the VAN page from displaying in its window.

Any ideas ???

My screen was hijacked by something lacked look like Mozilla/Firefox heading saying it was taking a survey and I couldn't get out of the screen. So I took the survey and entered my credit card info for a sum of $1.00 (one dollar) for a chance to win an iPhone. Instead I got a charge on my credit card from lstfl.com for $33.+ dollars saying it enrolled me in a sex site. That is NOT what I imagined. And it came under Mozilla/Firefox name. Can you go after this site as it is operating under your name and logo. Thank you

Updated Firefox to 65.0.1 yesterday now a number of websites do not work including firefox support site (Will not let me log in, had to download Opera just to post this issue.)

Examples include Facebook not loading all content or allowing me to follow links (Links do not work at all.)

Youtube can't play single videos (Again acts like link is not a link.) Playlists will somewhat work if you right click and open link in a new tab but only play about 5-10 seconds of a video before moving to a new one for another 5-10 seconds of play while also taking a lot longer than normal (more than the usual 2-3 seconds from before the upgrade) to start the next video link 10-15 seconds.

Would add info from "about:support" but it will not allow me to attach a pdf (The only way I can do that since "Automatically add" button reqires using Firefox and I can't right now(Not logging in.)

As stated before no log in ability on the support site here.

Most other sites I have tested are missing content or links randomly work or not with no real reason, at least any that I can figure some work some don't and some work some times but not others.

I have done a full un-install and re-install to see if that had any effect and it did not. Also this is the only change to my computer in a little over a month, just the update to Firefox 65.0.1.

Displaying website wrongly in fullscreen mode only - strip at the bottom of the screen

I'm using Firefox 65.0.1 (64-bit) on Windows 10 Home (1809) OS build 17763.292. When I open Firefox on full-screen on my laptop screen, there's a strip at the bottom of the screen, hiding the bottom of the website page I'm on. The strip is like a screen shot from a previous website I might have visited. This doesn't happen if I'm not in full-screen mode, and strangely it doesn't happen if I drag the same Firefox window onto my external monitor (HDMI connected, 1080p, 24 inch). The phenomenon occurs in Private mode as well. Anyone knows anything about this bug? Is there a fix?

I noticed that firefox stays in memory after I close it. In fact, If I open and close firefox 10 times, ten processes are shown in memory, each consuming around 100Mb.

I'm using Windows 7 in my corporate computer and I have been using Firefox 65.0.1 x64. I've tried to use it in safe mode (no add-ons) and problem persisted. I uninstalled it, deleted all Mozilla data in AppData and ProgramData and reinstalled it fresh. The problem persisted.

Then I installed the 32-bit version of Firefox and the problem is no more. Is it a bug that has to be fixed or some setting that shoudn't be enabled?

Thank you.

That Firefox page is completely frozen. Nothing works. But another Firefox page does work.

1. Synced my Firefox sync account

2. Disconnected my Firefox sync account

3. Reinstalled windows

4. Installed Firefox 56 (I was using 63 but i only had 56 installer)

5. Updated it to 65.0.1.

6. Connected my Firefox sync account


Problem -

1. All bookmarks didn't sync.

I created bookmark HTML backups and it were of 6mb and my latest backup is 171mb.

There are 2980 differences in 173mb backup and Backup taken after again connecting to FirefoxSync. I used WinMerge.

2. HTML backups also contain fav-icons [and Firefox Sync only syncs links not fav-icons.]

When browser is used fav-icons are loaded but after sync fav-icons are loaded as pages are loaded , so there are no fav-icons and html backup size is less than the last backup.

3. Could be related to https://support.mozilla.org/en-US/questions/1251781

4. There could be something wrong with Firefox's Exporting. Imported the same 173mb HTML to chrome and Firefox then exported HTML backups. Firefox Export was of 61.1Mb Chrome Export was of 12.9Mb
