Firefox 技術支援討論區

When I created my account FF did not prompt me for the login information. When I return to the site FF does not respond to the login request. I have been using FF for years and never had it not respond to login request. I do not receive any errors

I tweaked my Firefox configs to get better font rendering because I hate how "skinny" they are by default on windows. The options changed are:

• gfx.font_rendering.cleartype_params.rendering_mode to 5
• gfx.font_rendering.cleartype_params.force_gdi_classic_for_families to ""
• gfx.font_rendering.cleartype_params.enhanced_contrast to 100
• gfx.font_rendering.cleartype_params.cleartype_level to 100
• gfx.font_rendering.cleartype_params.pixel_structure to 1
• gfx.webrender.quality.force-subpixel-aa-where-possible to true

After the update, the fonts are default again, and no matter how much I change the configs, it doesn't change anything.

Hello everyone, I was here recently since nothing in Firefox wanted to load, but I fixed that by using old sessionstore.jsonlz4 so I guess that session was corrupted.

New problem: Everyday when I start my PC and Firefox it keeps crashing over and over until I use an old working sessionstore file again. So it seems that everytime Firefox tries to save my current session with nothing changed/ different from the backup it corrupts it and I have to use the old backup again - which obviously sucks since no matter what I open/ do today it will be "deleted" again tomorrow.

The only "interesting" thing the crash report shows is MozCrashReason: Failed to load critical module "resource://gre/modules/WebNavigation.jsm" but I will share the troubleshooting information below if that helps.

My only idea left is to save the most important tabs and wipe everything else off my Firefox to see if that helps - but if it doesnt then I have to restore my old session yet again and all progress is lost again no matter what I do.

Any ideas are appreciated especially since I didnt change anything relevant about my system or Firefox in recent times so I have no Idea where all of these problems come from all of a sudden.

Hi, I am a photographer, and am currently working on my website. I don't know how this happened, but I noticed a mysterious Pin It icon on my site early January. I had a Pinterest account (unused), which I deleted, thinking I could get rid of this pesky thing. Now I have no Pinterest account, but 2 Pin It icons. Bizarrely, they only show up on Firefox, not Chrome. (I use Firefox 99% of the time.) Could you please advise me? Thank you very much, Anne Saint-Pierre

After the last upgrade my bookmarks disappeared. What happened? Saved passwords too. History too. Also want to add that it is difficult to get support when needed. Maybe I need to go with Safari.

every time I first try and full screen a video it will not correctly fill the screen. if i go back to windowed and full screen again it will be fixed, and will remain fixed for as long as firefox is still open. if I close firefox and open again it does the same thing. See screenshot for problem.

When I click a link on page, or an app tries to open a tab (eg to print an ebay invoice), it opens and immediately closes the first time, but stays open the second time. It's really annoying.

In troubleshoot mode, it doesn't happen.

I am using FF109.0 and Linux Mint - 001-1.0 fresh install on new HD.

I had the same problem last year after I upgraded FF but did fix it eventually (can't remember how) Thanks

How I can set the browser to open a specific page every time the browser opens up, like my email. I saw where it can open to the last previous pgs that were open, but that’s NOT what I want.

Put very simply, Firefox Breaks Fedex site. I cannot login to fedex with firefox, but I can with Edge. I would much rather use Firefox. Is McAfee causing this problem?

My cable TV provider (ZIGGO, Netherlands) offers an extra service which makes it possible to watch TV with a normal browser, in my case FireFox 109.0 64b. You can watch 'live' and watch recent programs. Playing live gives only few amounts of harddisk write access. However (!!!) when I playback a recent program, Firefox writes 55 Mbyte/s to 2 caches on ..\AppData\Roaming\Mozilla and ..\AppData\Local\Mozilla. I was stupified when I discovered that 3 hours of watching recent programs wrote 1700 GB (1.7 TB) to my SSD by FireFox (according to Windows 10 Task Manager). This data is produced by FireFox since my 30 days usage of internet was only 30GB. I assume FireFox writes decompressed video to cache or something. I made a temporary fix by using symbolic links from ..\AppData to an old fashioned harddisk, which has a hard time writing, when looking "non live". I looked if ZIGGO installed some kind of plugin, but could not find it.

After Firefox’s latest update (109.0 - 64-bit) I am experiencing several bugs.

I’ve narrowed it down to two things:

• Context and dropdown menus do not appear, yet they are present (if I click where they would be the intended behavior happens). This happens for both the menu bar and the toolbar, as well as when doing right click in any website.

• I cannot move tabs along the tab bar.

No extension is causing this since I have disabled all of them.

Is some else experiencing these or similar issues?

If these are not common problems, does anyone know what could be causing them and how to solve them?

Thanks in advance!

Sites such as Chatroulette just show a black screen rather than video. Seemingly the issue is sites that allow Video chatting don't show any video incoming from other users. Stranger still, is that it is still able to access my camera so I can see my feed, but If i click to watch my feed, that is also just a black screen. Not sure if it is a plug in, I don't get any pop-ups asking for permissions or access.

Several times now when I access my banking site and export data, the exported data is not correct. Sometimes columns are missing or columns are in the wrong order. One time even the display showed missing columns. Another example is when I look up a stock quote, sometimes the numbers from previous days are displayed. Troubleshooting with the site manager we found if I cleared cache and cookies, the problem went away. Everything works for several days, then the problem reappears.

Clearing the cookies is simple enough but then I have to be re-verified on all of the sites that require such and that becomes a real pain. (ie. We are sending you a text, please enter the number to continue)

Google Chrome and Microsoft Edge both work fine with this site. Please don't make me switch but I will if this continues.

After downloading the latest update this morning in desperation, Firefox crashed on first character of the primary password again and again and again. This time, started new tab, tried to type L into the address line and Firefox crashed AGAIN. Eventually, I have found that if I open a new tab and input a character into the address bar, I get one of three results. a) I input L and an L appears. If that happens, I can go on to use Firefox. b) I input L and get a totally random character appear. Could be S, or £ or $ or something else. In which case, I can't use Firefox. c) Firefox crashes.

Whoa, that sounds really severe. When this happens, is the Mozilla Crash Reporter dialog coming up? If so, you can share your crash reports with Mozilla Support volunteers for feedback on what might be causing that. See: https://support.mozilla.org/kb/firefox-crashes-asking-support

Yes, this is the 6th attempt to start Firefox and keep it going beyond the first keystroke input. I keep restarting till it works. I do not do anything else except restart, then try to input a keystroke. I can copy and paste and all is well till I hit enter or some other keystroke. It sucks and the Firefox team must be getting mad at the crash reports. Taking out all the plugins didn't help, and neither did restart in safe mode. I just keep getting the same problem.

_05: chrome browser network panel after refreshing 5 times domContentLoaded: 328ms

_06: firefox browser network panel after refreshing 5 times domContentLoaded: 1880ms (5.73x slower)

the problem seems from that the request from firefox gets 200 wheras chrome gets 304 unmodified, which explains the huge speed difference in reloading.
