Firefox Version 63.0 (64-bit) Home build PC, 480GB SSD, 2 x 2TB HD's, 8GB Ram.

I have had problems with streaming Channel 4 TV UK for many years. I could only get it to work on Windows. Recently I have Dumped Window 10 - so slow - updates take all day. I now am using Ubuntu 18.04 LTS (using Linux since 2009)

Channel 4 say they Do Not support Linux ?

I have tried to install Adobe Flash Player, but does not seam to work or download. On Ch 4 web page I pressed Allow, but say that I should install Flash Player !

Please could anyone advice me what I can do, or what I have done wrong.

Regards, Richard.

Hi here!! I review a lot of mozilla docs (out dated or without complete info), forums, googling ... about how to share firefox/thunderbird/ligthing data between platforms on dual/multiple boot system. Every user in same trouble are repeating (copy/paste) in the solution to share the SAME FULL PROFILE on all platforms. I review profile data and folders and I can see files and config data that are platform dependent; then I think that share FULL PROFILE between is not the best approach, for example Linux and Windows will produce several problems (and a lot of problems with the add-ons) In these same mozilla docs recommends to share only data and maintain custom profile for each platform, but not more info how to do it. Please can some kind advanced :) provide some info about the correct approach. Or a better tech info about how is possible the recommendation of sharing same profile between platforms without problems. Because with the current doc info, there is no way to get a clear answer (Almost I can't :~). Thx guys!

When I right click, a left click is immediately fired which causes the first item to be selected. This is frustrating because the menu closes immediately.

Not sure what's going on. I tried downgrading Firefox and I tried a fresh profile. Nothing seemed to resolve this.

Initially I thought this was maybe a GTK3 issue, but I does not occur any other GTK3 application.

Any help?

Thank, Disco-Dave

This is a hard one to provide steps for reproduction. The next time it happens I will take a screenshot.

The issue is as follows:

I'm on a 64 bit Ubuntu 18.04.2 LTS machine, with Firefox 66.0.3 installed. Every now and then (roughly once every 1 or 2 hours) I will do something in the browser, whether that be open a new tab, press play on a YouTube window or something else, the window will turn invisible. The frame of the window with the name of the tab up the top is still there, and I can drag it around no problem, but the actual content of the window is not there, I can see straight through it. At this point I've sort of ruled out it being an OS related issue, as Firefox is the only program on my system that seems to have this issue.

Any help would be much appreciated.

I tried Fennec F-Droid, a Firefox version built from source without proprietary code, signed into Firefox Sync, but after renaming the device, the device manager kept showing it as the default name. Changed two or three names, then gave up and installed regular Firefox. Now when I click on "Send Tab to Device" the menu shows the names I entered for the device which were not working, but the device manager shows only the actually connected devices, so those names are saved somewhere. This error is persistent with all the devices I synced. How do I remove them?

Firefox seems to react fine, but it has a few weird issues. It will crash when opening or saving certain settings. It is also not able to open most of the folders in my home directory. Only my Desktop and Downloads folders are visible, along with some hidden folders. (files within desktop are vissible). The list of visible files is very limited. I've included a screenshot.

Accessing this help page to post this caused a crash as well.

Hi, my installation of Firefox 52.4.1 ESR is crashing reproducibly when I'm not using Safe Mode on certain sites, like Google Maps and Reddit.

I have created a completely new profile without add-ons and themes, and disabled hardware acceleration. Firefox still crashes on these sites. Only starting Firefox in Safe Mode solves the problem.

The problem only occurs on my tower PC which has a NVIDIA GPU, and not on my Thinkpad. Both are running the exact same Firefox version on Arch Linux with identical add-ons and user profiles. So it may be problem with video acceleration, but as I stated, I disabled HW acceleration. Btw. the problem doesn't occur with Firefox Quantum which I don't want to use until the most important add-ons are ported.

Anybody got an idea?

Hello. I had naively let my computer do an upgrade of Mozilla. Guess what. All data gone. History, bookmarks, add-ons. I didn't have a back-up of bookmarks, well, at least not recent.

How can I get them back? I've spent a lot of time with setting up Firefox so it would be comfortable to me, I've spent my time in it, and now it's all gone and I don't even remember the name of some add-ons I used to use.

Running Linux Mint, Firefox is latest version, PC has 8GB of RAM, yet when running Firefox gradually uses more and more ram till all is gone, only fix, close and restart Firefox.

Removed all addons, no change! SET Prevent Accessibility Services from accessing your browser to true, no change! Under performance set content process limit to 1, no change (I suspect this is a fake setting, it has no effect on number of processes!!)

PS Everyone else I know that uses Firefox has the same problem, is Mozilla trying to kill it?

I've been using Ubuntu 16.04 LTS and had immediately installed Opera as that was the browser I was used to but I quickly noticed that my cookies would automatically be removed when I shutdown making browsing a problem, so I reverted back to Firefox but it crashes quite often and the interval between the crashing seems to be growing smaller.

This will always happen with the Epson TM-T20 printer after successfully printing approximately 40 receipts. After restarting Firefox the problem is repeated.

The printer driver is the latest version 5.09E of 2018-01-15 but the driver version does not affect this issue.

I have tested individual versions of Firefox with factory default settings. This problem first appeared in version 50.0b1. Firefox 49.0.2 and older work well with this printer.
