Firefox 技術支援討論區

I can play videos and audios on another browser or files stored on my computer, but just now I cannot on Firefox. I saw the FAQ explanation about Windows 7, but I have been using Firefox for years including just hours ago using Windows 7. Why would this happen right now? Did some new version just get installed? If so, can I return to the prior version and turn off the automatic update?

Thanks, Phil

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

Resize or enlarge is not working well after browser stay opened more than few minutes, only close and re-open of the browser work: https://drive.google.com/file/d/1_8PtMgoyxvHFcXyddJXkr8z4rfmSLhkM/view?usp=sharing About my browser: https://i.imgur.com/Uwy68UQ.png My linux is: Ubuntu 22.04 firefox installed by Snap.

Firefox is the only application affected (latest 107.0.1, Windows 11 pro latest updates). I have updated all drivers, run system and memory checks, uninstalled deleted remaining files and registry settings, twice actually all to no avail.

I have recently changed ISP but cannot see how that affects just Firefox (Chrome/Opera/Edge all work) and also moved to Bit Defender antivirus. Here I think I saw startup installations in Chrome etc for bit defender but never for Firefox. I have tried turning off all virus web protection still no joy.

I have looked briefly at the crash reports but with my level of expertise I can see no common crash reason.

I have had no add-ins installed for last week while trying to get this to work again. I have used Firefox for years and have no wish to move to another browser but this situation is driving me nuts.

If there is anybody out there with any ideas on next steps I could take?

Cheers Mike

i click on the download folder in firebox and doesn't open as its used to.

i already did the "refresh" and didnt word

if someone has a idea how to fix this, thanks

Hi, It would be of great help to me if you could give me an advice how to fix my Firefox browser in order to be able to use it with sound. It used to work untill a few months ago, but once, with no reason, just stopped playing sounds , no matter if I accessed a news channel, Youtube or other site that uses sounds.. for this purpose I am forced to use Chrome or Microsoft Edge, but I like more Firefox. I mention that I have an i7 laptop with a Windows 10 OS. Thank you.

Please my firefox appears to have crashed, or is not working how can i fix it. As i try to open firefox document a dialogue box appears saying that either the firefox is not designed to run or that i should reinstall firefox

why are some of my YouTube videos not showing up at all in FIREFOX? also says I don't have access to "community tab" on Youtube which I do. None of these problems with GOOGLE CHROME - why is Firefox being so glitchy? its become a terrible browser.

Well, I have applied all the options about proxy settings with the same result of long time for opening websites when first start of firefox. During these months I took notice to the one point, i.e. if I open website using firefox in the earlier morning there is no problem with the speed of opening as well as if I open another browser of edge the last one opens website without any delay. So the challenge of long time opening websites when the first start of firefox is still in force. How to resolve this?

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

It turns out the copied logins-backupjson file i had pasted on my desktop screen was already overwritten by an added or removed login, thus writing over when it did have the saved login removed that i was trying to recover

is there any other way to recover the removed login?

i saw this response by Cor-el for another user with a similar situation

If you still have the signons.sqlite that was used in a previous Firefox version then you can try to restore passwords saved in that file.

Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file that has been used before (the matching key3.db file is still needed). If you still have the signons.sqlite file used in previous Firefox versions then you can try to force Firefox to migrate the passwords saved in that file (you will lose passwords saved in Firefox 32+ versions). You can force Firefox to reimport the passwords from the signons.sqlite file and rebuild the logins.json file with these steps:

   reset the signon.importedFromSqlite pref on the about:config page to the default value via the right-click context menu
   delete the logins.json file in the Firefox profile folder with Firefox closed 

When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.

Hello there! So, I've just installed Firefox in a notebook I have and now there's a website where I can't see some pictures. https://i.imgur.com/E86dhVB.png There should be a picture there instead of (IMG:link) https://i.imgur.com/7lzrbfU.png There should also be a picture there, behind "Redvirux". Some pictures are shown, though, but most aren't. It's an http website, but it had been working fine on my Windows 8 instalation. Do I need some codecs? Is it a Windows 10 problem?

Please fix the abovementioned problems,make a browser bit faster,improve the consistancy of the browser so that it will stop crushing.Please make it stop alternating or change mail pages.

I've had Firefox issues for months now. It started after the update three updates ago. Firefox would take 10-15 minutes to load, I often couldn't load websites even after it had loaded....except for a couple of nights recently I've been able to use it flawlessly. Like right now. It's almost 11pm and it's working. I've been through the clear the cache, check if the extensions are slowing it down etc. routine. So why is it working now? It probably won't work in the morning, it didn't work last night, but it worked a few nights ago and again tonight. I'm sorry this sounds so strange but I don't know what to do. I've had to use a different browser for a while but would love to come back to Firefox again.

My work consists mainly of capturing accounting data online. It is important that the browser warns me if I try to close or navigate away from a page if the data entered has not been saved or updated, but I no longer get these warnings.

Please help.

I have MS One Drive. In the last week I cannot connect to it from my online Outlook mail page. I have tried using Edge and Chrome and it works fine on these browsers.

Can you help me resolve this problem please.
