When I try to run Firefox, I get a window pop up says System Error X The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem. I downloaded Firefox & tried to open it & got the same error. Any suggestions about how to fix this problem & not lose my bookmarks?

I read that Firefox will using the Snap version by default on Ubuntu 21.10 and beyond. Will the non-Snap version still be available in lets say Ubuntu 22.04 and beyond? The reason I ask is because I use Firejail to sandbox Firefox and Firejail doesn't work with Snaps and yes I know that Snaps and Flatpacks both sandbox apps but I prefer Firejail because of the Private Home profile (nothing is saved in this profile settings, bookmarks, add-ons etc) its way more secure than the sandbox offered by a Snap.

In one of my windows, 9 out of 10 pinned tabs have been lost and replaced with "new tab" (which are all empty, of course).

The only unusual thing I can remember was using a private window a few days ago (a feature that I had never used before). Is this the cause of this bug???

Thanks.

Why is my FF keeps on filling up memory even without doing any browsing?

Because my FF started crashing a couple of days ago, I just monitored the Memory Usage on Task Manager. I opened both FF and Edge, without any browsing. Edge is maintaining memory usage at around 129MB (without browsing), but FF keeps on increasing the memory usage. About 20 mins since opening FF, FF memory usage is 3,241 MB (without any browsing at all) and it still keeps climbing as I type.

I am attaching a couple of Task Manager screen shots.

Edge memory usage is up on Image 4 because I am using Edge to type this message.

Can someone please help?

(Current FF memory usage is 3,518 MB - no browsing at all).

I use Win 10 and I'm up to date.

================

Update: (1) I refreshed FF which stopped continuous increase of memory usage (while not browsing). Also, I could see FF lines disappear from Task Manager almost immediately on exiting FF.

(2) To get back "quick launch shortcuts" I copied file "Pref.js" from my old profile. Continuous memory use while idling started again. FF lines were still there on Task Manager after exiting FF.

I generally have loads of tabs open, and until recently this wasn’t an issue (perhaps until last upgrade?), but now, I can hardly move between tabs, the drop down list showing tab selection doesn’t work, nor does the left/right arrows. When I delete a tab, it leaves a ‘space’ where the tab was, only ‘back filling’ after I’ve opened up another tab to full screen mode and then minimised it again, at which point it goes to the very left-most tab and the only way I can get to tabs further down the list, is by deleting them in the manner described. I’ve actually got 2 laptops (Win 7 & 8.1), and it’s now happening on both of them. This might have something to do with memory management/the computer’s page file, but as things stand, I’m SERIOUSLY going to be switching to another browser - despite sticking with Firefox for many-a-year. BTW, I’m actually writing this on my phone, as I couldn’t now do it on either of my laptops (hence I’m currently unable to attach anything/provide screen grabs etc. I guess the only way to ‘clear’ this issue, would be to either close/restart Firefox or my laptop - neither of which I really want to do. Is there a way that I can use an earlier version of the browser and prevent it automatically updating? Yours, a now very frustrated longtime user,

Occasionally some websites will render a few icons of some particular type in a weird way. It's this crisscrossed celtic-looking pattern of yellow green and red. It's not a monitor or GPU issue, although does sort of look like my GPU is broken.

Here's an example. Curiously enough, this happens occasionally but here are some concrete examples where it ALWAYS happens. On 10forums, EVERYONE'S profile looks this way. https://www.tenforums.com/drivers-hardware/111899-stereo-mix-no-longer-appears.html

(look in pictures)

And so this didn't matter because this happened like once when I was doing a captcha, the whole captcha was rendered weird, and on tenforums. And almost never anywhere else.

But okay now it's a problem. A newgrounds game is rendering weird. (image attached) The boxes move around a tiny bit, they walk up and down.

I have to use chrome to fix this issue.

Anyone know I should do? I'm like 80% confident I've tried disabling ALL extensions but didn't fix the issue. I can try again if you really think it's important.

I just updated Firefox to 92.0. (Windows 7 Pro, SP1, 64bit) I am visually impaired, and use one of the Windows high-contrast modes to be able to read the screen. The 92.0 update absolutely "broke" the high-contrast mode. It is now almost impossible for me to view any website... I need some sort of fix... NOW. I either need instructions to back up to the previous Firefox release or instructions to add or change something in "preferences" if that is possible.

Hi,

I'm Windows user and Firefox stopped loading web pages one day. I tried to reinstall including %APPDATA% deletion but nothing helped. I also deleted the Mozilla directory in Program Files. No matter if I use default or no proxy.

I also tried to delete some Firefox items in Register with no success. I cannot disable the Windows Antivirus since it's a company laptop. Chrome and Edge work just fine.

Can you pls advise what could cause the issue?

About a week ago, Firefox began occasionally opening a webpage or even my Google login window in some random language. Opening a new tab and closing the errant tab would result in the same page opening correctly in English. The language used when Firefox erred was never the same twice.

I have three devices, a desk top, a laptop and an iPad. The desktop is running a very outdated version of Firefox which means it is not compatable just to update it. The forum tried to help me with this a while back, but it was deemed not to be possible, and the best way would have been to do a fresh new install, but there was noway to save log-ins/passwords bookmarks. My devices all have the Firefox sync and that is so far working well. My question is, if I dragged my PC's Firefox into the present by performing a fresh new install, would my synced items install ok....after invoking the Sync feature on the new install. Logic tells me this should be so, as it worked ok with the new iPad, but I know from experience that logic doesn't always come into play. (Windows7) Many thanks
