Firefox nightly (trunk) 100.0a1 (2022-03-10) (64-bit) (but previous version too) is crashing the tab if the page contains video content. It happens also in "Troubleshoot Mode". It doesn't happen in 98.0 (64-bit)

I have been having problems accessing part of a membership site. Can't get past the first step, it doesn't work for me.

Kubuntu 20.04.4 LTS Release: 20.04 Codename: focal Firefox Version 98.0 (64 bit)

Have been informed from the website owner that the IT person has tested this with Explorer, Safari and Chrome, and all work. The IT support person then goes on to state - "....... that the client needs to use a different browser as Firefox is very outdated."

So, I was using the latest version and it is "very outdated"  ???

How can I respond ? Is there a training course for the IT person to deepen their skill level ?

Adblock Plus - is it safe? Why Mozilla doesn't recommended it? I used it in the past some years ago but now I am scary about safety

Dear Community,

I would like to download this extension: https://addons.mozilla.org/pl/firefox/addon/adblock-plus/ I would like to know how it works. If I will install this extension my firefox will be check hashsum for the files of this extension automatically? Or maybe public key of the organization/company who created Adblock Plus extension? How it is work? Can you tell me? I hope that people from Mozilla now read this and can answer for my question. This is very important for me.

Next question is to Adblock Plus extension. I can read this information: "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing" so my question is why Mozilla don't recommended this extension? This extension now use 6,678,297 people so this is huge count. It is possible that this extension is not safe and these people now use malicious software? Why on dedicated website for this extension I can't see company name? Why this company is not verified by Mozilla? So my sugestion for people from Mozilla is to change this and check this extension or maybe add some information on website for this extension.

So I should install this extension? My friend use this on Google Chrome and he recommended me this software but I don't know if this is exatcly the same version. Maybe Chrome has verified Adblock Plus software and this is safe but Mozilla didn't verified this and this can be dangerous software because this can be not exactly the same version?

Next question is to adblocker. Why Mozilla can't make their own software to block all annoying ads and due to fight with malware? Example Opera browser have own buil-in adblocker. Why firefox can't do this? Maybe people from Mozilla should do this? This can be helpful because if this can be happen I will be not install any 3rd party software for firefox anymore and I will be safe. Maybe I can send somehow this suggestion to people from Firefox?

I hope that you can help me.

Yours faithfully, Peter

When entering credit card info in a web form, Firefox will pop up a dialog asking if I'd like to save the card info. If I click yes, the dialog closes but the info is not saved. If I go into settings where one can view the saved cards and enter the info to save a new one, I can enter one but again it does not actually save. There is no error, it just doesn't save. Tailing journalctl shows no errors, and launching Firefox from a console and watching the output doesn't show any error either.

It's been this way over several updates over the course of a few months (as long as I've been using Firefox on this computer).

Hi, how do we set Firefox 97 to use the os/system print dialog?

Before Firefox 97 we could change these settings in about:config:

print.tab_modal.enabled = false widget.use-xdg-desktop-portal = true

But they are both gone now.

There is now widget.use-xdg-desktop-portal.print, which is an integer (2 by default).

But no matter what integer it is set to, we still don't get the os/system print dialog.

We are using Arch Linux, but we don't expect that to be of any importance -- after all, it worked before Firefox 97.

Thanks for your time :o)

I've checked a couple of the "similar topics" before posting here. I'm not sure if I am having the same problem or something else.

Back Story: I have a "few" windows and tabs open in FireFox. I would finish what I was doing, shut down and then the next time I booted up and loaded FireFox, all sessions would be restored and all log ins honoured (kept). That is: I was still logged in.

(Moving to now) Yesterday I powered up and ALL sites were logged out. About 20 log ins were needed. Hmmmmm... gmail, and the rest.

"Ok... something happened. No problems, things should be ok from now. I've logged in, so all is sweet."

Today I power up: All logs ins lost. Had to go through it all again.

Gmail is throwing security alerts at me hand over fist. Yeah, that is good in some ways. I get that part. But I've logged in.

Seems - my thoughts - that the cookies aren't being saved. But why? I haven't touched them or their settings.

Yes, I did do a clean out of older cookies. But left the gmail ones, and other sites I know I use. I have `adblocker ultimate` installed.

Now I am logged in, if I open the `cookies` and look I should see them there for the sites to which I am logged in - yes?


To be clear: When I am done, I do NOT `exit` FireFox. All windows, tabs, sessions are left. I just shut down the machine. Then next time I load FireFox and they are re-loaded and log ins are maintained.

Hello SUMO Team!

  I always had this question but never really asked it. Why isn't DuckDuckGo or a more privacy based Search engine set as default? You even have to manually add Startpage and others... 

 It just hurts me how a privacy browser has the Google search engine as default after all, most people come to Firefox for privacy and Google is the opposite. Maybe one of the developers can change that?

Thank you so much for trying to help me and Stay Safe!

Dear community,

Transferring my passwords from an old profile backup (v 49) to a profile in a newer version of Firefox (v 77.01). I'm copying across the logins.json and key4.db files like it says here: https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile#w_passwords. but it still doesn't seem to show my passwords in the new Firefox version when I look in the preferences. I did happen to notice that the key file version is named 'key3.db' in the old profile whereas the corresponding file in the new profile is 'key4.db'. I don't think they're compatible. My question is can I move my passwords from the old profile to the new profile in Firefox v 77.01? Please can you tell me if I can do it offline/locally like this? I don't want to do it with Firefox sync. I'm currently having problems signing into Firefox sync so that isn't an option.

Kind regards,

Matt

I've installed Nightly the same way I have for years on my latest Fedora 33 install—i.e., download tarball, extract into /opt, set appropriate chmod and chown, make .desktop file, etc.—but certain videos certain videos on certain sites refuse to play. A Fedora discussion discussion led me to think it's how Fedora 33 may sandbox apps; I haven't yet had any hits on solutions in the Fedora groups, so I thought I'd ask here, since I can't be the only one with this issue.

Any help would be greatly appreciated!

When I'm using my Firefox for too long or few couple of minutes its suddenly fronzen and stops response. So I need to restart it, killing the process using top,htop or kill commands. It has been weeks that this problem started. I waited for updates and tried reinstall it, but no futher SO updates and reinstall solved the problem, if the new Firefox release updates could put a end to this problem.

I have here some ID number of my bug report that I send to Mozilla, if someone could help understand if its a package/driver or miss configuration I would like to know.

bp-8764ac27-aa1c-4db5-831c-ae2460211031 bp-87b0281c-aae3-418e-8f45-828f20211031 bp-d01fcb65-6123-499a-a3d8-4c7950211031 bp-83d56e36-0d58-4456-a7e5-677370211031 bp-a385f497-2271-4120-bdbb-474440211031 bp-f320a744-5606-4743-87ab-763620211031 bp-4a2d704e-cf83-4eb5-8df0-c10b70211031

When press the upper right button 'x' to close, it says that my Firefox isn't respond due to: 'Firefox: Exiting due to channel error'

I don't know how to fix it or find better logs messages to discover what is happens on the Firefox. I have SO with Windows 10 and I don't have this problem at all.

(Firefox 94.0; Fedora 34; Gnome)

When I go to some video websites and click the play button, I see the little circular thing in the image are spinning, indicating that the video is loading. But it never stops and it never plays. Also, the pause button does not have any effect; the loading indicator keeps spinning. Example website: "https://proclassictv.com/" (both with "The Rifleman" and "My Favorite Martian" episodes. I've tried this on a few of the videos available there. Same result. I've tried this with add-ons enabled and with add-ons disabled (current session). I've seen this in a few other websites also. I don't know if the problem is my system, Firefox, or the host website.

I am able to view youtube videos with no problems.

How do I get the videos to play?

Thank-you.

Running Linux Mint Mate 19.2 on two computers. Starting about 2 weeks ago, when trying to sign into providencejournal.com (with a paid subscription) using Firefox 97.0.1, just one of the computers displays an error message, see attached. We have used that site for years without issues, and the other computer still signs in correctly. On the problem computer I have just installed the Opera browser, for test purposes, and with Opera the sign-in succeeds. In F/F, I have tried disabling extensions, allowing all trackers and cookies, and reinstalling Javascript, all to no avail. preference is to use F/F, can anyone offer a solution?

I'm sure it is not Firefox as I have also tried Chrome and Opera; same problem. How can I debug this and find out why the video cannot be played ?

I see there is 'Remote Debugging' and 'Browser Console' under 'More Tools'. How do I use these or other tools to find out what is causing the problem please ?

I support open source movement and against tech giants and hence I love and want to use Firefox. I would use Firefox even if it is slow because on most sites delay of few seconds doesn't matter. But I do stock market trading and trading website of my broker (finvasia.com) is very slow in Firefox. On all chromium based browsers slowness is not there.

In trading delay of even one second is a matter of profit and loss (specially in scalping) and hence using Firefox is not possible as it is very slow for finvasia.com.

I have done screen recordings to give an idea of degree of slowness. First video is when finvisa is opened in a chromium based browser MIN. As you can see that when I change from holdings to position etc then delay is very less. (the yellow circle on the screen hardly complete one complete rotation and holding or position scree is opened). In this video you can also see that when I place order or modify it, everything happens so quickly.

Finvasia on chromium based browser

But in the below video (finvasia in firefox) you can see that when I switch from holding to position (00:2) the yellow circle (just above the pointer) makes 9 complete circle before showing the screen. When I click on Buy button on order screen (00:34) the order doesn't get fulfilled (the order rectangle didn't disappear). At 00:47 it said connection issue (There is no connection issue, wifi is working fine and never show any connection issue in chromium based browsers but in Firefox it shows in every order).

I kept waiting but order rectangle didn't go so finally I had to close it manually (1:45). After that when I switched to order screen it didn't show any single order. I tried to refresh the order screen (1:59) but nothing happened. So finally I refreshed the tab of browser. It was also hanged and after few click it worked and then you can see that there were many orders on order screen.

Finvasia on Firefox

As trading involves money and such delay can cause huge loss. Trading on Finvaisa.com is not possible if a person is using Firefox.

I also tried safe mode, and refreshing the Firefox, but problem didn't get solved. Kindly fix this problem.

Firefox version is latest (99) and I am attaching screenshot to give details about my system and OS.
