I-Firefox Isithangami Sokwesekwa

My default search engine is Wikipedia. I cannot reset it from preferences -> search. There were two posts just like mine back in 2013. The solutions to those posts (2 links) have expired.

[Observed Behavior] Downloading does not start. If try to close Firefox, remaining downloading popup is displayed

[Expected behavior] Succeed to download

Previous Firefox do not have this issue

Hi fellow Mozillians,

I've had this issue for a while now but haven't been bothered to look for answers.

I seem to get an issue with vertical banding of images.

My Firefox 84 is now in an endless loop with updates.

It asked me to download an update from version 84.0.1.

After Firefox closes, installs updates, and restarts, it comes back asking me to update again.

The cycle continues and the updates never complete.

In the Help...About box, the button is still there "Restart to Update Firefox".

I'm using 32-bit Windows 7.

Images attached.

Please advise.

Thanks!

Long time Firefox user here - been on from the start (about 2005), and don't want to switch because I love some features like the Panorama View extension, Context Search extension etc, and it's always been a great browser.

Recently though (not sure if it's just recently, or I've only just noticed), it's so slow. I tried a brand new profile, no extensions, no settings changes, and it's the same. Example loading times:

bbc.co.uk/news Firefox: 14s Edge: 2s chess.com Firefox: 19s Edge: 4s chess.com play vs computer Firefox 38s Edge 2s

https://youtu.be/er9jBysL0vEFirefox vs Edge (YouTube)

So it's not my profile settings or extensions.

BUT, I tried it on a different user profile on the same computer (Switch User from the Windows Start menu), and it's fast!

Why is this, and what do I need to do on my user account to speed Firefox up (keeping my same Firefox profile)?

Thanks in advance.

For the past few days, my browser has started trying to save all JPEG files, regardless of their actual fire extension, as .jif. (see attached photo) I have not changed anything that should have done that, and cannot seem to change it back. Any help would be much appreciated!

The first attached image is a worst case. Scrolling and/or moving the cursor usually avoids the problem. Sometimes reloading the page is necessary.

This is occurring on two new machines: Dell Inspiron 15 5000 Series 5502 with intel 11th gen i5 processors and intel iRISxe graphics. It happens with Ubuntu 20.04 FFox 84.0 and it does not happen with Windows 10 and FFox 84.0.1 (I think 84.0.1) I can re-boot and check if that matters. It does not happen on Ubuntu with other browsers (Opera and Chrome).

Disabling the plugins and even removing them does not help. Safe mode helps.

What else can I provide to document this?

So I've noticed how some video files are able to be played back in Firefox. Some are not able to what so ever, for example I've created a text video using this FFPMEG command: ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 testsrc.mp4

which created the following file: https://astolfo.nl/i/z2ada.mp4 Both the uploaded version and the local .mp4 are unable to be played back in Firefox. However opening them up in edge chromium both files play back perfectly. Besides Edge I've also confirmed it plays back nicely in MPV.

I've tried Hardware acceleration, but both having it on and off did not change the fact that these files wouldn't want to playback in Firefox. Safe mode also did not effect this issue.

I cant open Firefox - screen/ window comes up with message: Firefox can't find the file at jar:file:///Applications/Firefox.app/Contents/Resources/browser/omni.ja!/chrome/en-GB/locale/branding/browserconfig.properties.

How do I get back to a usual opening of firefox?

I'm having a new problem with Firefox, which I think appeared with Firefox 84 (but I'm not 100% sure). When I type in some text boxes, the cursor gets very slow and unresponsive to move around by the keyboard _if_ the text in the box is long enough so that a scrollbar appears on the right hand side. Sometimes. It doesn't happen at all sites -- it's not duplicating in this textbox that I'm typing in right now -- but it happens all of the time in the message boxes at playdiplomacy.com, and sometimes on GitHub.com when posting issues. Sporadically and unreliably.

As far as I can tell, the cursor is still moving quickly and responsively, but the blink itself isn't happening so I can't see it. If I hold down the left cursor key, it looks like the cursor isn't going anywhere, but if I hit a letter key that letter appears instantly at the location where the cursor has apparently moved to, with no delay.

The problem does not occur when I hold down shift (to highlight) while moving the cursor via the arrow keys, which further suggests that it is somehow related to the cursor blinking.

Restarting in safe mode makes the problem go away instantly. Disabling all add-ons myself does not. Starting with a brand new profile does _not_ make the problem go away either. So there's something safe mode is doing that a new profile doesn't.

Any idea what might be causing this?

(Ubuntu 20.04, Firefox 84.0).

Thanks!

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

After the last update (Version 84.0.1), I can't search on Aliexpress for products. I can write in the search box, but when I press search button, nothing happens. Nothing happens even I choose from the search suggestions too. I'm very upset. I've installed opera browser and searching works well. Everyday updates for nothing!

Hi all,

I've been having problems with firefox lagging constantly. General browsing around feels laggy - and opening new tabs pretty much causes my computer to freeze for a few seconds. During this time firefox causes the CPU to spike to 100% usage.

I've been using firefox for years on this computer with no issues. Hardware is pretty good (i7 5820k, 64GB of ram and an SSD).

So far I have tried:

• Running in safe mode

• Using a different profile

• Downgrading to an older firefox

• Changing allowed CPU cores from 8, to 4

• Updated graphic card drivers to latest version

None of these work, and I'm getting a bit tired of the constant slow downs. Chrome works flawlessly, as does all my other software...

Any ideas?

Thanks!

Recently (within the last few days) tabs have began crashing on youtube. Specifically if a video player page is loaded, but the player itself is paused for any length of time.

I have tried and successfully reproduced the issue with safe mode, I've also successfully reproduced the issue with a new profile. I've also successfully reproduced the issue with an entirely new ~/.mozilla directory.

It appears (based on what I can see) something on the page is triggered, then memory spikes and the tab crashes.

What else should I try to resolve this?

Hi all,

I'm struggling with certain downloads and Firefox when using a web proxy. The proxy settings are done in Windows 10 and Firefox is set to use system proxy settings. Users are authenticated automatically at the proxy using kerberos (Windows AD environment)

On the proxy (Squid) I can see the failing files downloaded and I can download these files being transferred to firefox via the proxy port when doing packet capture. Nearly all sites and services work. Only some are affected. When using other browsers (MS IE, MS Edge, Chrome) these downloads work perfectly. When disabling Proxy on Firefox these downloads work, too. Only with this combination Firefox + Proxy I get some failures.

This is one example (that's a PDF datasheet): https://www.ergoswiss.com/de/services/cad-hydraulikhubsysteme/pumpen/pumpe-pf-3-4-anschluesse/?tx_downloads_downloadscategory%5Bdownload%5D=1753&tx_downloads_downloadscategory%5Baction%5D=download&tx_downloads_downloadscategory%5Bcontroller%5D=Download&cHash=9351869892df2bd6c6fbebbd2e74e862

And this is the error message Firefox gives me: C:\Users\[changed for privacy]\AppData\Local\Temp\64gqW0kX.pdf.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator

Again this works in Firefox without proxy and It works in the three other browsers with and without proxy. And only few files are affected. Besides checking logs and doing packet capture I'm running out of ideas. Where do I continue troubleshooting?
