I have set Nightly as my default browser on Fedora 27, but whenever I click a link in some app, Nightly will just open a blank window. Regular Firefox works fine, though. I've tried switching to GNOME on Xorg to see if it's a Wayland issue, but the problem persists...

Hey! When I want to go to paypal.com I get an error message with the title "Warning: Potential Security Risk Ahead". Below the title it says: "Nightly detected a potential security threat and did not continue to www.paypal.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

www.paypal.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Nightly can only connect to it securely. You can’t add an exception to visit this site."

I don't think PayPal is in-secure.

I tried many answers I found here, like going to about:config and changing security.tls.version.max from the default of 4 to 3 etc.

Again asking for help to turn off the popup urlbar "pic related",I have asked the same question back then in Nightly version 75.0a1 when this (irritating) feature was introduced and I tried the same steps but setting "browser.urlbar.update1" to "false" doesn't work.

is this permanent? if so why? if I wanted a bulky UI I would just use the Touch Mode or the Normal Mode, at least give us the option to turn it off/on, my problem with this is 1- it ruins the Perfect aesthetic of the UI and make FF looks like Quasimodo (just saying FF has the best UI out there) 2- it overlaps with other elements of the Compact UI like the bookmarks toolbar making it irritating as a "Jack Russell terrier"

and do me please a favor Don't ruin the compact UI

I was running Firefox Nightly, opened about:profiles and launched a new instance with a different profile from there. At this time, the green update icon indicated there was an update in queue which was then installed right before starting the new Firefox instance, while the old instance was still running. At first everything was fine, my other profile launched, I did my work, closed it and after some more time also closed my main profile. But then when I restarted Nightly, it brought up a Mozilla Crash Report pretty much instantly... My profile is broken

I could work-around this by starting Firefox Beta which prompted me to Refresh the profile... Now I can launch Firefox again, but all the settings from about:config and my extension settings are gone. Is there any way to bring back those settings?

I made a backup of the profile before the refresh so I'm positive the data is still somewhere... However, just copying the profile.js file doesn't work, then I will get the prompt again to refresh my profile...

Using the latest Nightly version which I update every day. For the last couple of weeks the tabs will crash as soon as I open Nightly unless I am in Safe Mode. That said, I do not have any add-ons or extensions enabled other than the default Mozilla ones. Running the system report, it does list 14 extensions that do show up when I simply use the menu to open the add-ons/extensions page. I am attaching my about:support info. Anyway, I wonder if it is one of these extensions that is causing the problem since being in safe mode prevents the crashes from happening. At first I thought it was a universal problem and if I simply kept updating the program it would fix the problem but since it has persisted this long I am guessing it is something unique to me.... Thanks for your help, Dan

Beginning with Firefox 40, if I:

- go to http://semrush.com/
- search for a domain (e.g. "mozilla.org")

Firefox becomes almost completely unresponsive.

E10s is enabled, but I get the same results in a "New non-e10s" window, or by starting with a new clean profile.

I have tried with Firefox 39 and it works fine. Can anyone else confirm the problem?

Thanks.

Hi to all!

I'm on Firefox Nightly 71.0a1 (2019-09-20) (64-bit) on Arch Linux. I'd like to watch a mov video, embedded in a website. The video is fine but the control shows it as muted. Indeed there's no sound. If I click on the sound control of the embedded video player, I can't toggle the sound control, which stays muted. The controls works on Chromium so it's not a problem of a video with no sound.

Thanks a lot for your help!

EDIT: I've tried with other mov files. I went to the Apple site: https://trailers.apple.com/trailers/focus_features/downton-abbey/ I can watch the clip with sound but here the audio control can't be toggle or change: the volume stays at the same level.

Starting Tuesday 5/27, something with Nightly changed that broke Yahoo mail for me. IE works, but is too buggy and insecure for me. Firefox works, but it's slow. I want my Nightly back, but if I can't get any work done or check my mail with it, it's less than worthless.

DISCLAIMER: I found many articles about this issue, but none of them solved this problem.


DESCRIPTION: I have a problem with Firefox on my backup PCs that makes it freeze/slow down everytime i try to • play more gifs at once • play HTML5/Flash video on high quality/bitrate or loading more post on facebook. • Simmilar action that require system resources.

I believe that firefox won't use all available system resources. This issue always occur on "load" and system resources are always around 30-50% of use based on Windows 10 task manager (near usual load on my backup PC without running services/programs s it still uses only around 10% of resources).

NOTE: This issue is notable mostly on my backup PC with limited performance, but i found simmilar issues on main PC. The difference is that on main PC it uses enough resources to run without notable performance drop.

This problem is on firefox only (tested on chrome and edge).

END-USER OPINION: I believe that there is problem in firefox settings that prevents it to use all system resources.

TRIED SOLUTIONS: • Reinstall flash = Without effect • Tries Firefox stable build = Without effect. • Disable/Enable hardware acceleration = Without effect.

• Reinstall Firefox using iobit uninstaller to remove all registry and perform clean installation of firefox. > Without effect.

• Installing different firefox versions. > Without effect.

• Running firefox without extensions. > Without effect with ads and white stuff that prints stuff into my retina.

• Messing up with about:config. > Mostly more harm then good done and even then when i try to change one at a time and verify its effect on system i cant seem to find anything that could affect firefox performance to solve this problem.

• Forcing videos to use HTML5 instead of flash and conversely. > It won't play HTML5 on youtube and flash is lagging on higger bitrate. I believe that it won't play HTML5 due my youtube settings HTML5 worked fine on other sources.


Thanks for help! - DK

I have 3 sites in my homepage settings. First two, I keep pinned. Third is a regular tab. When I close and reopen firefox, for whatever reason it will open duplicates of the 2 pinned tabs, as regular tabs. So I have 2 pinned tabs and 3 regular tabs instead of 2 and 1. Why is this happening?

Using Firefox nightly. Happens on regular Firefox stable release too.

Firefox nightly has started using around 4Gb memory. Looking through the memory information in Troubleshooting, I find this under the heading "Other Measurements"

134,217,727.94 MB (100.0%) -- address-space
├──134,216,156.60 MB (100.0%) ── free(segments=195)
└────────1,571.34 MB (00.00%) ++ (2 tiny)

Does Firefox have a memory leak of poor garbage collection for the free space to be almost 100% of the allocation i this area and the space used to keep creeping up. A daily reboot is required.

What I do see is E-bay pages having loads and loads of Google advertising frames. Like they are created and never released but new ones created latter.
