Firefox 技術支援討論區

I just spent 15 minutes browsing and downloading a lot of images. When I was done I looked at my downloads folder and saw only half of them there. I checked the download history in firefox, and couldn't see some files. They were not queued or in progress. They weren't in the download list at all.

I reproduced this. I downloaded an image again. Right click, save as, click save. Then that image doesn't appear in the download history.

I tried some variations. Hitting enter instead of clicking save. Opening the image in a new tab and using ctrl-s.

Still, no image in the download history or on disk.

I quit firefox and re-openned. Still the file didn't appear on disk or in the download history.

Then I kept trying, and I got a second issue, which I think is related.

Often when I save an image, instead of one window popping up asking me where to save it, I get a second window popping up ontop of that, then a third, then a fourth. All ontop of each other. All asking the same thing. They take the focus, so it's not possible to interact with the main firefox window to continue browsing.

Sometimes if I hit enter literally 50 times then it will save the same image repeatedly, and eventually I can go back to browsing.

Sometimes there's more than 50 popup windows (my hunch is more than 100). My only solution then is to quit firefox forcefully. Which is annoying if I have state in other tabs that I don't want to lose.

This has happened many times over many weeks. It only happens on some file saves. I can't figure out why it happens on some, not others. (Right click > save, and also ctrl-s, they both do the same thing.)

This form won't let me attach a screen recording. Only screenshots. That's annoying because you can't really see the behavior from the screenshot. But I'll try. See the dark black border outside the download dialogue? That's normally a very faint transparent shadow. But because there's so many duplicate windows all exactly ontop of each other, those multiple transparent shadows have become opaque.

What you can't see from a static screenshot is that I could see each window appear ontop of the other. If I try to select the filename text and edit it, very quickly another window appears ontop with the default filename again. I can see the Firefox icon in the Gnome bar on the left shaking every time a new window pops up.

(Hmm, it looks like I can't *upload* screenshots either. I click browse, select a file, and then it doesn't get uploaded.)

I'm on Ubuntu 22.10 with Wayland.

I don't know if this issue is a bug in Firefox, or in Gnome. I've only seen this behavior with Firefox in Gnome. Not Firefox on another DE/OS. And not any other application in Gnome. This behavior has been intermittent since I bought this laptop and installed Ubuntu about a month ago.

I was browsing and commenting on a YouTube video, when my my typing wasn't showing up for several seconds after I typed it...like 20-30 seconds. I checked Windows Task Master and 10 instances of firefox were open (I was only using one tab) and they were using 68% of my CPU and 90% of my available memory, basically locking up my computer. I tried closing it and reopening it, but the same thing happened. I had to go to another browser. I remember this happening in the past, and I had to move to another browser permanently. I would much rather stay with Firefox if you can prevent this from happening.

thanks.

I updated. There was then supposed to be a 're-store session'. Didn't happen. And I'm not about to read a thousand pages of twaddle to find out why. Firefox actually just sucks. My tech installed it. I'm going back to Safari.

When using Firefox on OSX (Ventura 13.4) after about 1 day Firefox slows down so much I have to quit the application and restart it. Then it is back to normal speed. I'm not sure if this is an OS-X issue or Firefox issue, but restarting the app fixes it for a few hours, then its incredible slow again.

After updating to version 114 I keep having tabs crash. If I close Firefox and reopen it, the first few tabs are fine. After a bit, any tab I try to open gives me a "tab crashed" message. I can only load the default tab screen. If I try to go to Google or anywhere it crashes. I try to do a search and it crashes. I've had to use Chrome to be able to do anything.

In the last month Firefox using google search simply refuses to search, this is becoming annoying to the point where I will start using other browsers. Is there a fix for this?

I recently switch to Firefox and I'm enjoying it so far. One problem though, continuously using Firefox over a long period of time cause it to use more memory than normal. I assumed it was because of the large amount of tabs i kept opened but even when i had closed most of them, the problem still persist. This lead to worse performance and more frequent crashes. One way I found to have helped is to close and reopen Firefox, but the fix is only temporally.

Since I updated to version 113.0.2 every time I try to open certain websites, Firefox shows an error message "SEC_ERROR_UNKNOWN_ISSUER". Once I choose to accept the risk and continue it redirects to the IP address "79.137.248.81" that redirects to spam. This happens on multiple sites, certain popular sites such as google work perfectly.

Yesterday I uninstalled and installed the browser. I rkilled and scanned my system with Malwarebytes, Avast and HitmanPro. I also have no malicious addons I found. Nothing worked.

I am attaching pictures of how the error shows.

Please Help.

Error: "Secure Connection Failed

When it happens: - Irregular frequence. The same websites once work once don't. They work with Chrom/Edge/From my mobile(same wifi/router). - Sometimes I have to refresh the page a few times - Happens for all sort of webistes. From local news, to GitHub/Youtube/Google/Any website

Steps I have taken: - Cleared cache/cookies - Reset PC/Firefox - Cleared all extensions - Deleted Firefox (And manually deleted all folders in AppData related to Firefox) and reinstalled afterwards

Nothing helped. Any idea what is going on? I checked Mozilla documentation for SSL issues, but it didn't help either

A month ago I started to have problem with twitch. After 5minutes or 2 hours- random times or random tabs, if I have opened more than 1, which is always the case. Some tabs or all, again it's random will give twitch 2000 error and refresh, closing tab,etc nothing will work, except closing WHOLE browser, not just tabs and this is not guaranteed that it will work.

I'm losing my mind with closing whole browser-windows-tabs on different monitors and then re-opening all of that again when I get 2000 error and I always do get it.

Did like 50 re-installs, it's always the same. I tried to go back to older version, but Firefox always want to create new profile saying I have old version installed and I DO NOT want that, I want everything as it is right customized,etc right now.

Just recently been experiencing the 400 Bad Request error on Kick.com (a live streaming platform) for about a couple hours now. Never had any issues prior.

Was informed that this same issue is happening on other browsers and the only solution is a "quick fix" (clear site cookies) which only works for literally a second. When the page is reloaded the error message pops back up.

Please help, thank you!

The last update 113.0.1 was when I really noticed it being slow. None of the current suggestions have any effect. I have restarted several times, cleared cookies and history, flushed dns and have gone through all settings. Privacy is set at "standard" and not using a VPN and have turned off add blockers with no effect either. I have to check, but I don't think I have any add-ons except for color on home page.

If I do a speed test, ping is kinda slow, download is half what it should be at times, and every test shows ZERO upload all using several sites to test from . The only thing not done is shutting down av which I won't do. Anyone else seeing this issue? Any other suggestions than the go-to stuff here? Windows 10
