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.

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

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?

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.

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.

I've been using my banking site for many years on my desktop computer. Today the site comes up but when I try to log in I get a "404" error message. I tried logging in with Edge and there was no problem. I have deleted all my banking cookies on Mozilla and the result is the same. This is a major problem and I would appreciate any suggestions.

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.

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,

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 !

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.

I noticed an issue since I updated to Firefox 89. Usually, when I right-click anywhere on the page to bring up a context menu and then decide I don't want to use any of the options on it, I can click on the page and the context menu disappears. Now, though, they don't go away unless I hit escape. I tried Firefox with the proton options enabled and disabled and in safe mode and regular mode and without any css personalization and it is the same regardless. Is this a bug? I'm on Windows 10 laptop.

I got new computer and keep getting an error message that says, "The code execution cannot proceed because VCRRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." I have reinstalled multiple times and keep getting the same message. Any advice on how to fix this would be greatly appreciated.

After allowing the latest version of Firefox to update (89.0) I can no longer access my bank's website. Any suggestions on how to fix this problem would be appreciated.

BTW, I did not like the new theme offered so I changed browser.proton.contextmenus, doorhangers, modals, and places-tooltip to false. Not sure if this would cause a problem and I will set them back to true and test.

Oops! Nevermind!

After writing the above sentence about changing the proton settings, I went back to verify what I had done and found that I had left the browser.proton.places-tooltip set to 'True'. I switched it to false. Now all browser. proton settings are false and access to the bank website functions again.

Since Firefox has been updated, the interface is completely unusable. The frame does not render properly. I can use Firefox only in safe-mode with the terminal. The new WebRender seems to be the problem.

What did I do then ?

• I entered apt purge firefox for full removal and reinstall -> Didn't work.
• I disabled in about:preferences hardware acceleration -> Didn't work
• Downgrade to Firefox 88 -> Worked.

I love the new interface and the new render process. But if I can't use it on my home workstation, things are going to be hard for me.

I added a screenshot to show the problem.

Thanks by advance !

Today I switched from Chrome to Firefox. Since I have two monitors one common thing I do is opening a new tab and then dragging it (the tab not the window) to my second monitor. But when I do this firefox freezes and the only I can do is stopping firefox via Tasmanager and starting it again. I also tried it in debug mode and the same thing happened. I can replicate 100% of the time.

As of yesterday's update I cannot access Hotmail or Gmail through FireFox! I can do so in the private browser which I don't want to have to use AND I can access both through other browsers but would prefer to stick with FireFox if only they'd stop screwing their customers up so often! I DID EDIT THE URLs CONTAINED IN THE SHORTCUTS ON THE BROWSER'S OPENING PAGE TO JUST BASIC DOMAIN NAMES BUT NOTHING HAPPENED AND NOTHING CHANGED THE RESPONSE OF FIREFOX! Can anyone please help? I am so fed up!

Here are the website urls that will no longer open from the browser page (screen shot provided) https://outlook.live.com for hotmail (& it wouldn't open even before editing) https://mail.google.com for gmail (& it wouldn't open even before editing)

Thanks.

PS there was a post last year of the identical issue but the solution she used isn't working here!

I have an older PC but it was working fine with Netflix and Prime Video until this latest update (v89.0). It seems that when I try to go to Netflix or Amazon Prime Video the browser crashes almost instantly, and usually shuts my whole computer off. It doesn't go to a blue screen, the computer just decides it's time to reboot. Now again, I'm using an older machine (and I can't afford a new one), but this was never a problem until this latest version of Firefox.

I am also not a fan of the aesthetics in this version and I'm wondering if I can revert back to an older version where the crashing was less frequent. Any help would be appreciated.

I am running Firefox 87.0 on Ubuntu 21.04. I ran into some issues after an ubuntu update, where programs (even gnome-terminal) stopped loading all together after I boot into my system. I resolved it by forcing modprobe.blacklist=nouveau

Now my system can boot, and all other programs work fine. However, while my firefox opens up properly, it doesn't load any pages. Not even the Preferences and about:config page. If I remove all tabs, and open a new one, it would repeatly prompt me that Firefox needs to restart after update. Although restarting firefox does absolutely nothing.

I've tried creating new profiles, rebooting my system, completely removing and reinstalling firefox, nothing works.

I'm forced to install and use google chrome to ask for any suggestions, which, as you can see, works perfectly. Please save me from this hell.

Hello,

Firefox crashes on startup since version 89. The crash doesn't happen in Troubleshoot Mode.

I have tried everything following "The problem does not occur in Troubleshoot Mode" on this page, but it does not help. https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems#w_the-problem-does-not-occur-in-troubleshoot-mode
