Firefox supportforum

seemingly at random, images displayed in firefox will look incredibly messed up (like artifacting, and discolored chunks or stripes), text will be missing (as small as a few letters or as much as a page having no visible text at all), text will be discolored (usually a bright color like neon green or pink), and/or or text will appear blocky (sometimes manifesting as the font looking a little thicker and less HD, sometimes as bad as just being illegible rectangles). text with missing letters is able to be read while highlighted, but text that has become blocky is still unable to be read (still blocky) even while highlighted. i don't know if discolored text is affected by highlighting.

these issues happen regardless of what website i'm on, and will also happen on new tab pages or on firefox settings pages. it isn't consistent, it comes and goes. refreshing the page doesn't help or change anything, but if i close the tab and then navigate to the page again it's often different.

i've attached all the examples i've thought to capture, which isn't much. it can make the browser practically unusable at times.

i have firefox version 89.0 (64bit, auto updates enabled), on a windows 10 with 8GB of RAM and AMD FX-9800P RADEON R7 (i honestly.. don't know what that part means, but thought it could help) i previously had "Use recommended performance settings" and "Use hardware acceleration when available" enabled in firefox, but i turned them both off in an attempt to fix the problem. it didn't help.

i can't say for sure when this issue began, as i haven't used firefox much until recently, but i think it's been happening for over a month now. none of the other programs i use appear to be having visual problems, just firefox. at some point a year or more ago, i ran firefox on this computer without issue.

Hello,

After installing some random extension (pinned tab whats app or something like that), my firefox starts to act weird. I have big stripe/band on top of barely every website I use (as seen on attached screenshots).

I uninstalled the extension right away but it doesn't fix the issue. So I uninstalled entirely firefox, deleted what I found as my use profile folder, made a fresh install, but the issue is still here.

It disappear in troubleshooting mode, but in normal mode even with no extension the bug is still here.

When displaying developer tools, the page is now totally blank on some site, normal on others.

I'm on Elementary Os 5.1 (ubuntu 18.04).

Many thanks in advance for your help !

Bonjour, depuis plusieurs semaines j'ai des bugs graphiques sur l'interface de Firefox et sur les pages web. J'ai attendu en pensant que ça passerait avec une nouvelle mise à jour mais rien ne passe. J'ai testé le mode dépannage et le mode réparer Firefox, le problème persiste.

Hello I have almost 10 tabs opened. I tried to refresh one of them but didn`t respond. Then I tried another one but didn`t respond either. So I closed Firefox and reopend it. A popup appeared for some seconds with the warning that there is a missing dll and may be a reinstall could fix the problem. I did so (without unistalling Firefox) but still the problem remains. Every time I open Firefox, all tabs appear, but the address bar is blank in all of them and back-forward and refresh tabs are grey. Any Help please? Thank you.

Whenever I try to type into duckduckgo serach box my address bar pops up and it goes into that instead of the search engine search box. I have tried to change search from address bar to search box in settings yet it still happens. Started with 89 build.

After a crash, or even after shutting down the computer without closing all Firefox windows, Firefox will restore all the windows and tabs from the last session on restarting Firefox.

There can be many reasons why this may not be preferred behaviour for many users: Sometimes Firefox or the computer crashes because too many windows and tabs are open (and other applications running), killing Firefox may be a measure against malicious pages trying to hijack the browser, discarded pages after shutdown do not need to be restored, ...

So is there a way to make Firefox immediately ask whether to restore the session, like it already does after the second crash? This should actually be an option in the settings.

If I right click on a webpage the context menu opens. If I then click outside the context menu it doesn't close, but stays open. If I move focus to the search bar (not the address bar), starts typing and select an item from the drop down list, the drop down list stay open. If I start typing in the address bar and select an item from the drop down lost, the drop down list stay open. If I click the Bookmark menu icon on the toolbar the drop down list with bookmarks open, but if I click outside the list, it doesn't close but stay open. The same thing happens with the program menu in Firefox. Even when I start a different program, the menus and drop down lists from Firefox stays open on top of the other program. The problem also happens when I run Firefox in Troubleshoot Mode.

Any ideas?

Hello community,

I had some problems with my internet connection. Youtube streams changed frequently their video quality. So I wanted to look up my downstream. To do that I have look into my browser and type the URL "http://fritz.box" into it.

The message I got was that this is not possible anymore (uploaded pic). I had to do it with Google Chrome. That's a disgrace for Mozilla.

I hope it will be possible soon again to surf into my router UI.

Sincerely yours

Mario

Following a Windows 10 update, I tried to open Firefox and the following popup message appeared. "the code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." I have tried several times to download the latest version of Firefox, but during it's installation the same error message appears. How can I fix this problem and get Firefox to work normally.

After updating to Firefox 89.0 there are no more default search engines, so searching for someting is no more possible. Clicking "Searching for default search engines" is not succesfull.

Hope someone can help, because there are not corresponding answers in the net.

After the Firefox upgrade to version 89, the icons disappeared from the menu. When I look at the changes page, I see that they have been specifically removed. In my case, the functionality of the Firefox menu has been severely compromised by losing those icons. So far, I’ve used those icons as a mechanism for faster navigation between different points. Because it is faster to recognize a single icon (character) than to read text. In the past, toolbar items overlapped menu items with icons. And now not. Not only that, the layout of the menu items has changed.

My suggestion would be to return the icons. And make them show / hide through settings.

I am not an English speaker, so I apologize if there are various errors in the text.

why every time I upload a file, firefox crashes. I've tried running the troubleshooting the problem is still there, my firefox version is up-to-date

this is my report ID : bp-9b2952cf-32f7-4838-b8ee-139b80210611 bp-2d34c8d9-aa8b-4204-89ca-ea6e60210611

For about a week now, I have been having issues using netflix and youtube with firefox. I have tried answers provided in other questions, such as emptying the cache and clearing cookies - which works! But only until I leave the page or change what I am watching. Netflix is especially frustrating as it requires me to go to netflix.com/clearcookies every time I use it - which means I also have to re-log in.

I have no idea why this is happening and am getting increasingly frustrated. The problem appears in safe-mode (troubleshooting mode) and I cannot find a permanent solution. Any help would be appreciated!

Hello,

after an update up to Firefox 89.0 (64bit) on my elementaryOS 5.1.7 (based on Ubuntu 18.04) I've got a grey-colored rectangle in the upper part of my window that overlays all elements of websites (cf. attached screenshot), however I still could pass via hyperlinks if there are any under the rectangle. It is very light grey in light mode and dark grey in dark mode.

I've tried following steps according to possible solutions found in the Internet : - launch Firefox in safe mode (the rectangle disappears) - make sure the default theme is used - turn on/off the hardware acceleration - update or disable and delete all add-ons and plug-ins (rectangle still present in normal mode) - delete and reinstall Firefox with wiping all its files on the local machine (including /home/user/.mozilla and /etc/firefox* folders) - delete again and install the flatpak version

Nothing of the above helps except of the safe mode. As I have tried already to delete add-ons and plug-ins, what else can I disable to try to solve the issue in normal mode ?

I would appreciate your help as this is the only browser that I (want to) use on a daily basis. Thanks in advance!

My Firefox can't play any video on any websites. Youtube video keeps on buffering forever and I can't click on the play button. But preview images still shows up when I hover the mouse over video bar. This happened after I updated to latest FF version

I've tried every solutions provided by Mozilla Support: clear caches, disable extensions, uncheck hardware acceleration,.... you name it I've tried it all. Other browsers are just fine, but since FF is my main browser for work I don't want to switch to another one just for music or video.

Thank you for your support.

Some solid colours on certain webpages do not appear whilst on Firefox. The background will show up instead of the colour the image should be. I have tried to delete the cookies and cache on Firefox as well as trying Firefox in troubleshoot mode to no avail. Whilst writing this question, I have also discovered that taking a screenshot of the issue shows how the image should look as opposed to what the screen shows. Attached are some images of the issues I am facing, two images are of what appears on the screen and one image is the screenshot from the webpage which is what should have been shown. Apologies for some of the photos, I had to take a photo of the screen with my phone to show the issue. I have also closed the browser multiple times and restarted my computer, any help would be appreciated. Thanks in advance.

Hi all,

I am running the latest version of FF and Win 10 64 bit. When I access our local DIY store, bunnings.com.au, I get an error message "some error occurred". Pressing F5 gets me to the site. This does not occur on Chrome, Edge or another PC with the same versions of FF and Win 10.

Running FF in troubleshoot mode does not resolve the issue, neither does clearing cache.

However, if I open google.com.au and search for bunnings, then click on the link in the result, I do not get the error.

Does any body have any ideas? AFAIK, it started when Bunnings moved to a new website design.

Regards,

Steve

Hello, I have trouble getting sound playback on firefox (checked 85.0 and 78.7.0esr both 64 bit) on windows 10. I checked sound on youtube, and netflix. I checked other applications like spotify and mpv, and soundplayback there is fine. Also it works on Firefox nightly (87.0a1).

What i have already tried: - restarting my computer - opening windows volume mixer and see if firefox is muted - updating my audio driver - different playback devices (Device over HDMI and Line out) - reinstalling firefox - uninstalling firefox, delete folders in C:\Users\$username\AppData\Local C:\Users\$username\AppData\Roaming - new install with fresh downloaded installer - restart to safe mode

Since firefox nightly is working i suspect that maybe the application name "Firefox" is muted somewhere. This could explain why i can reproduce my error on ESR and stable but not on nightly.

Thank you for your help in advance
