Diễn đàn hỗ trợ Firefox

Starting a couple of weeks ago, I began noticing that occasionally (every 2-3 days usually), a few empty files appear in my c:\ folder (Windows 10, as up-to-date as Windows ever is). They have names like "wal3A7109C6" (no file extension). Usually 4-5 will be generated at the same time (ie, same timestamp, so within the same second).

When I first noticed them, I (nervously) deleted a batch with no apparent consequences - but I had to activate Administrator privileges to get rid of them. I ran virus scans but have seen nothing unusual.

A few minutes ago, I had Firefox open but minimized to the task bar. I also happened to have c:\ open in a Window I could see. As I tapped to expand the browser, another of the files appeared, and the browser window behaved oddly for a moment, as though about to crash. The last few versions - I'm at 125.0.3 (64 bit) - have been crashing more than I'm accustomed to, but this is the first time I'd considered the browser to be a likely suspect.

Does anyone have any clues/possibilities to offer? It would be much appreciated.

May I first say that trying to get hold of you to make this report was painful, and took about 20 minutes and a long walk around Mozilla's assorted website, opening two accounts, etc.

I received a notice while using Firefox on PC that an update was available. I was going to put it off, as I had 25 tabs open, but the notice indicated that my open tabs would be restored once the update was complete, so I approved the update. It download and I assume installed the update, seemed to temporarily close Firefox, and then reopened the original page with all my open tabs, plus an empty page. When I tried to open the tabs shown, they all indicated that the tab had crashed and then gave me the option of restoring that tab or on some restoring all tabs. Neither worked, in fact, that Firefox page became completely unresponsive and would not allow me to browse new urls (the tabs just spun). I actually had to use MS Edge to get to anywhere to seek out someplace to make a report. I first went to the discussion group and opened up an account there, but from there noticed that feedback on Firefox was at a different url. I then needed to create an account "here". Since nothing was working, I closed and reopened the Firefox page with all the tabs on it, figuring maybe it would restore the crashed tabs. It did not and all tabs were lost. I can probably get back to some of them using the history archive, but it was very disappointing and will be even more time consuming. I am running the current version of Win 10 pro, 64 bit, on a PC. I thought you would want to know about this. Thank you for your time.

OS version : Windows 10 Pro 21H2 Browser version : Firefox Developer Edition 126.0 Beta 8 (20240501022718) Platform : windows, Web

EVERYTHING especially

 * The time to receive the first HTTP response when connecting
 * the time to call up the various css elements that make up the screen
 * the time to call up the img elements on the screen
is too slow.

tooooooooo slow. I waited 36.6s until http response for every new URL open! Of course, I am using a lot of Firefox extensions, but there were no serious problems outside of YouTube, and the same problem occurred after removing the extension, and i also confirmed that the problem caused by web extensions on waterfall(on firefox profiler) was minor.

I can't even guess the cause of the problem, so unfortunately there seems to be no additional information that I can give you. I'll keep following up as long as I can. I will attach some pictures that might help you solve the problem. and you can also approach to my full-recorded firefox profiler data

So for some reason I have two versions of Firefox on my computer (Windows 64 bit), I am logged in and using one of them, and the other is just there. I could log in there but I don't want to, I just want to get rid of it. Links from Telegram open in it, creating a second Firefox window instead of opening in another tab in the already open Firefox window, which is very inconvenient. The windows list of programs which can be uninstalled only has one Firefox (I've tried deleting and reinstalling, it doesn't help). But when I try to choose a default browser I get 2 icons to choose from which look the same (see screenshot). What the heck? How do I manage this!

I can no longer login to my webmail account using firefox, but I CAN login using MS Edge. I obtained a new ISP and set up a new email account. I was able to access the webmail account for about a month with Firefox. Then a few days a age, it just stopped: When entering valid credentials, the login page just refreshes (without errors) and doesn't continue to the webmail inbox any longer. So I thought I'd try a different browser and I used MS Edge. The valid credentials get me into the webmail inbox using Edge, but no longer works in Firefox. Any ideas what happened?

Every time I sign onto Firefox I get the attached message. I think that uninstalling Firefox and reinstalling "may" resolve the problem, but Firefox won't uninstall. I have tried four different ways and it won't uninstall. Can you help me an uninstall process?

Hi,

i am currently at a loss.

I have set up Passkeys for my google accounts. Now i have completely reinstalled my current pc and now there is no QR code showing when trying to log in.

I have another laptop where it will start completely normal. I can switch between a hardwarekey and another system (to show qr code)

Can you help me with this? I cant seem to understand why it is working on my laptop but not on my desktop. I just cant switch to log on with another device, now it is not even giving me the option to log on with a hardware key.

I would appreciate help.

Greetings

I am trying to add custom search engines to Firefox. I have tried the steps given in the forum thread https://support.mozilla.org/en-US/questions/1212596.

However when I try to go and add the search engine as per the article given above I do not get the option. Please see the attached screen shot for more details. I do not want to add an extension or a plugin, but just manually have the option of adding search engines.

New tab opens to blank page and not my home page, which is Google. I have been to setting and went to the drop down box for tab settings but it only gives me an option to make firefox my home page or a blank page. I want Google to be what appears in my new tab when I click on the little + isgn.

To check my icloud email, I log into icloud.com, enter my password, got through a two step authorization process and ask to stay signed in. I successfully access my email messages. When opening a message that has a hyperlink, I lose the iclolud connection. The link opens in a new browser window, but when i return to the email I am frequently signed out. Apple support does not know what the issue is; they suggested a different browser. This does not seem to happen with Microsoft Edge - and I don't want to use it.

Thanks for your help David Bartold; dwb0224@icloud.com

I downloaded the new update this morning and I cannot separate my categories any longer on my home page. I keep them in categories on the 4 separate rows and then separate them by skipping a square. I cannot do that any longer and do not like the jumble of the homepage now. How can I keep the blank spaces that are located at the bottom of the rows to separate my categories?

Some years ago I had to replace my PC and thought - Wonderful - just use sync to bring back all my tabs etc into the new PC...

The long and the short of it (in the past), was that Firefox decided that the new PC was the one to be synchronising source, and promptly removed all the apps/tabs etc. so sync was in line with the new PC - erasing all the app data. I understand there is no 'Master' sync account.

The question is, how can I stop Firefox initially migrating the Firefox app data in the wrong direction? I know that the app/tab data is currently still correct as my laptop still has all my apps etc. Is there some way to stop Firefox thinking the latest clean browser on the new PC has the correct (None) apps etc? Has the laptop to be logged-in and currently on-line before starting the new PC with Firefox? Is there a process to follow with a new 'un-synced' PC?

Sorry if I'm making things sound difficult, but don't want to loose everything which is currently correct and still these within sync data. It's maybe something that can't happen in these later versions of Firefox, but I want to be sure before logging in my new 'Blank' PC.

I'm about to give up on Firefox.

While Firefox is the browser of my choice, its bugs are a constant source of frustration. When navigating on YouTube, I'll suddenly have it stop loading properly and just load more or less blank. You can see this in the image attached. To rectify this problem, I'll need to quit Firefox completely and run a cleaner (WiseCleaner, in my instance) so that it loads correctly again. This happens across several computers I have.

As I game, I usually dual-monitor to watch things on YouTube or Twitch simultaneously. When watching Twitch with Firefox, I noticed that the video would stutter or freeze while the audio continued. I checked Task Manager and found CPU usage to be extremely high. I cannot recreate this problem now as my second monitor is in the repair shop.

Firefox is one of the only few alternatives to a Chromium-based browser. As I don't like Google policies on ad-blockers, tracking, and so on, I'd like to stay away from anything Chromium-based. But it's becoming increasingly difficult to do so, as the user experience in Firefox is so bad, especially when using YouTube, one of my main browsing activities.

I tried turning off hardware acceleration, but this did nothing. I've reinstalled Firefox, but as this happens across several unconnected browsers, I cannot think this is a local problem. What to do?

i recently lost some data i want to get back, and this may be my last attempt, but is it by any chance stored here? and if it is, how do i transfer it back to my regular cache/cookies/data/bookmark folders

hi can anyone tell me how to get my saved passwords back into ff. they got deleted somehow by Clean Disk app

instructions ive found on web are for everything except what i need thanks

Your help utility needs help. -results don't show date, must open each item. Results seem to not be listed in date order. What a mess to sort through. I can't select a desired date range, or select by release version number. -your search tool isn't very effective, I keep getting unrelated results. I do better by searching google to find the help I want regarding Firefox.

Hello,

My name is Grey, and I'm experiencing an issue using Firefox as a browser to open my Outlook mail. For the past three days I have not been able to open any emails as a network error screen appears. Using other devices and other browsers like Edge, the emails open fine, so it is not actually a network issue. This problem only occurs using Firefox, and specifically with Outlook emails. Everything else functions fine and I have not made any changes, besides the regular Firefox update. My computer is also up to date.

What can I do about this issue? I appreciate the advice,

grey

On every new release of an update for Firefox, the update process deletes all of my saved cookies that I have established an exception for. I do this so that I don't have to continually enter my user name and password for sites that I visit regularly. The developers must change the updates so that the exceptions carryover to the new version of Firefox.

Dear All

We have recently found out that Firefox doesn't sync with Google My Business listings as when you search for “Saffery Geneva” on Firefox it brings up “Saffery Champness SA”, while on Google it correctly appears as Saffery (Suisse) SA as per attached print screen.

Any idea why Firefox is not syncing with Google with respect to this listing?

Many thanks.

Anna
