Diễn đàn hỗ trợ Firefox

Firefox is having trouble loading certain pages, including with Facebook messenger but also a bunch of other sites. It'll just stop loading despite that the address is still in the toolbar and the screen is still white. If I refresh a few times, maybe go to a different part of the same website and navigate from there, I do always manage to get there, but not sure what the problem is. This problem is new this week, and I think came from either switching internet providers earlier this week or trying out "Hopin" the next day, a video conferencing platform that my computer/internet totally couldn't handle. (I didn't notice the problems before trying Hopin but perhaps I didn't notice that first day.)

I have cleared my cache and cookies, and have also tried (following the advice of another answer on the same issue) renaming the Firefox program folder and installing Firefox again. I'm on Windows 10, 64-bit HP laptop. My extensions are uBlock Origin, Privacy Badger, Malwarebytes, Honey, Facebook Container, and Colour -- but all of these I had long before this issue started.

When I try to screenshot and download an image it screenshots multiple images instead. My OS is Windows 10 and I'm having this problem when trying to screenshot and download an image from Instagram. I right click on the image as I always have and it screenshots and saves multiple images instead. I never had this problem before updating to Firefox 88 and I've been using the screenshot feature for well over two years. I tried uninstalling and reinstalling Firefox and I'm still having the same problem. The image I'm trying to save is the one on the upper right.

Hey, I want to make the UI slightly larger; I have found that modifying layout.css.devPixelsPerPx in about:config works the way I need it to. However, when using multiple screens with different resolutions, the scaling no longer appears consistent between those screens. That would make sense (since it's a per-pixel configuration), but I couldn't any configuration option that only acts as a modifier for the standard scaling mechanism. I'm using macOS (10.15.7), Firefox 88.0. Attaching a screenshot taken from both screens together (not sure how macOS handles the difference in resolution when handling screenshots, there's definitely some magic going on with macOS screenshots in general; either way, it shows the problem really well).

Hi, In continuation to this thread, https://support.mozilla.org/en-US/questions/1293344 , May i know if the decision to continue the support for Flash is still the end of June 2021 or has it already been decided to push until Sep/Oct end?

Can you help please?

My default browser is Firefox but I am having problems logging into my TSB internet banking. TSB now demand, in addition to the usual login details, a One Time Password sent to my phone which is supposed to last 90 days. This doesn't last 5 minutes let alone 90 days. I have also used Chrome and Edge to check if their browsers produce the same problem. There are no problems with either browser, the One Time Password lasts and login is straight forward. My Firefox is uptodate and the operating system is Windows 10. Any advice would be helpful as I've had none from TSB Thanks Roy.

Please help. I was trying to download a file from MediaFire, and a popup appeared. I tried to close it, but another one opened up. They were all trying to install an extension and saying "update Firefox" I accidentally clicked on one. It didn't do anything, but panicking, I Alt + F4'd a bunch of times and when I saw that they kept reopening, I shut off the computer. I came back, and I have no new programs, extensions or suspicious looking processes. As I'm writing this, Windows Defender is running a full scan.

Am I infected?

Suddendly the audio stopped coming from my headset, so I thought it was a problem with the headset itself, but then it works flawlessly with Chrome. How/where can I solve this problem? I hear the audio on my computer and not on the headset, but only if I use Firefox.

I, today, found that Firefox 88.0.1(64bit) sends "/nice%20ports%2C/Tri%6Eity.txt%2ebak" to an website. What is this? Am I infected? The Apache log at the HTTP server is as follows:

192.168.1.188 - - [10/May/2021:07:42:41 +0900] "GET / HTTP/1.1" 200 665 "-" "Mozilla/5.0" xps8940 192.168.1.188 - - [10/May/2021:07:42:42 +0900] "GET /nice%20ports%2C/Tri%6Eity.txt%2ebak HTTP/1.0" 403 - "-" "-" 192.168.1.188 192.168.1.188 - - [10/May/2021:07:42:42 +0900] "GET / HTTP/1.0" 403 - "-" "-" 192.168.1.188 192.168.1.188 - - [10/May/2021:07:43:58 +0900] "GET /Picture/MicroS5S.gif HTTP/1.1" 200 3042 "http://wista.jp/Index.htm" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0" xps8940

The server is located within my home LAN. 192.168.1.188 and xps8940 is the captioned machine that sends this unknown protocol. Tested by Chrome and found no such protocol sent. Could any guru enlighten me? Tak

Firefox will not now open in Windows 10 but opens in safe mode. When I try to open in windows 10 I keep getting error code: XUL Runner Error: Platform version "88.0.1" is not compatible with minVersion > = 88.0 maxVersion > = 88.0

and Firefox does not open.

My video download button has disappeared. I tried re-downloading it but still no button. I then tried numerous downloaders and none of them display a download button. What is going on??

I use iCloud.com for my email. A couple days ago my launched message windows (such as opening or replying to a message) will not come forward of the main screen. The tabs appear as thumbnail previews (see attached), but will not display on top. They stay behind the main window screen and cannot be used.

I am on current Firefox version (88.0.1), and did several refreshes which would fix it temporarily, but then it reverts back. I did a complete uninstall and re-installed, but this still has not fixed the problem.

This appears to be only on this PC: I have another almost identical box where Firefox displays the iCloud tabs correctly.

I'm now having to use MS Edge to send or reply to messages from iCloud.

Sometimes i missclick at folder at bookmark panel instead only 1 bookmark. How i can prevent opening all bookmarks in folder. Just do nothing. Or at least get the warning - "You really want open 10 tabs" /

It used to be like this: when u selected a file to print (for exemple: a .pdf attached in email) it opened in a new tab, with a preview. Not it seems this is not happening, and when i select it to print, it just download the file. There's a lot of files that i don't want to download, i just want them to be printed. How should i do?

I'm on macOS using firefox 85

Thank you.

Something strange happening with my Firefox for a few months, you can see the screens below. Letters disappear (but visible under selection or Ctrl+A), images are broken (but totally fine after being saved on PC), and all these acid green and pink parts make internet surfing a challenge. Refreshing pages doesn't help.

I tried deleting and reinstalling Firefox anew, without all plugins and stuff but the problem still was there. Cleaned the system with CCleaner, checked with ESET Internet Security. Google Chrome, Windows file explorer and all other programs are totally fine.

Please help!
