For the past 8-10 days, every time I try to log-on to: https://selfservice.telkom.co.za/rococo/public/content/interstitial I click "Login" under the Mobile & Home heading and I receive the following message returned.

Bad Request The request could not be understood by server due to malformed syntax.

I have used MS EDGE browser and do not get the same problem, it log's-on OK.

As such it seems that it is a Firefox problem.

I get so choppy scrolling that my eyes hurt after few minutes. Doesn't happen on Chrome or Edge. It is most noticable on YouTube. It feels like it's running at 15fps

I'm having the exact same problem that

https://support.mozilla.org/en-US/questions/1157490

firefox itself opens and loads within seconds perfectly fine,[...] But when I try to go to any website, it takes ages to load and function normally. [...]

Once it has loaded the website(s) it functions completely normally

As the solution in that thread was a full format I'm reopening this to find a more precise solution.

I tried everything on that thread without success. Deactivated every plug-in and the problem persist. Running in safe-mode corrects the problem.

I attach an image of the profiler (I can send the full profile if needed)

Bonjour, Depuis une semaine, j'ai ce message à l'ouverture de ma page d'accueil Orange, avec Firefox !! PR_END_OF_FILE_ERROR il n'y a qu'avec mon navigateur et pas sur Chrome ni Edge. Avant, j'étais le seul impacté par ce problème et maintenant les trois P.C de la maison le sont. Deux W11 et un W10. En déconnectant le VPN le souci n'existe plus. Merci d'avance pour votre aide.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

google.com and google related websites doesn't load at all. For example, gmail slowly loads, but loading icon never disappears, loading icon is always shown and then often it shows 'reconnecting' message. This works OK in Chrome.

Steps to reproduce: 1. Open Firefox without VPN - all loads well. 2. Enable VPN - stops loading. If I then disable VPN - it starts loading again.

If I restart Firefox it starts working OK, but after a while stops working again.

A white screen occurs when browsing the web. If you turn off "Use recommended performance settings" and "Use hardware acceleration when available" the problem is fixed, but then the browser slows down. Can this be fixed in another way?

Firefox 114.0 (64-bit) / Windows 11 Home 21H2

Hi all

I'm a happy user of FF but have started to see issues with JavaScript (error message: You need to enable JavaScript to run this app.). I do the about:config correction and it sometimes works, but now the error is spreading to involve other pages - a page worked yesterday doesn't work today.

Is it just me?

Can someone help? I'm close to abandoning Firefox, which I don't really want to do.

1. When I open Firefox, I get the following error on the landing page (google.com):

Secure Connection Failed

An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

2. When I navigate to a non-secure website, either by typing in the URL or using a bookmark, I get the following error:

The connection was reset

The connection to the server was reset while the page was loading.

   The site could be temporarily unavailable or too busy. Try again in a few moments.

3. When I navigate to a secure website, it works and I can log in to log in screens for financial accounts, etc.

4. I'm running Windows 10 on a PC and Firefox version 97.0.1. My Firefox on my Android works fine.

5. My only extensions are Adblock plus, Cisco Web Extension for Webex meetings, Javascript toggler, and Video Download helper. I have no Themes downloaded, and my only plug-ins are one added automatically by Mozilla (OpenH264 Video) and one added by Google (Widevine content decryption).

6. I've checked all of the proxy settings, all of the https only settings, and I've disabled each and all combinations of the extensions including reboots of the computer after each trial change - but nothing works.

Anybody have any ideas? Anybody experiencing this? It's been happening since about the last three Firefox updates. I keep waiting for an update to fix this, but it isn't happening.

Help, please?

Until several weeks ago, new windows created through Javascript with window.open() worked. We could pass the new size, and other features, e.g. menubar, toolbar, etc. and they would show up. As of v.76.0 this is no longer true. The parameters are ignored. If we use no parameters, the menubar, etc. do show, but we can't control any new window features. We have not changed our programs at all, and window.open() parameters still work correctly in Chrome, Brave, Edge, etc. How do we get Firefox to recognize the window.open() parameters (again)?

Since the OS upgrade, any portal that I open (especially the ones that I have my user id and password saved) crashes. One crash report can be found at https://crash-stats.mozilla.org/report/index/7d671357-2d98-4bbc-b177-4029e0221221

I have tried disabling add-ons/ exensions, disabling auto-fill, downgrading security, reinstalling (even the ESR edition), deleting Firefox files from the library/application_support - but it doesn't simply work. Not sure if this is an OS issue.

Any ideas would really help. Getting the below info on the about:crashes each time:

Crash Reason EXC_BAD_ACCESS / KERN_INVALID_ADDRESS Crash Address 0x0000000000000018

Hello, I hope someone can help me.

Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.

The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.

Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.

Thank you in advance.

When I click on a "mailto" link, Firefox (my default browser) opens a new tab, then immediately close that tab without waiting for my to interact with it. No draft email is created. I see that other users have reported this behavior in the past, and I've tried the suggested remedies without success. Specifically, I ran Malwarebytes, and it found no threats. I then started Firefox (on the Mac) via the Option key (to start it without ad-ons), and that does not change the behavior. I'm on ver 99.0.1 of FF, which is up to date as of 4/20/2022 (today). My Mac OS is also up to date (ver 12.3.1). My Mac is a 2021 MacBookPro with the Apple M1 Pro chip. I use gmail. OTHER BROWSER (like Safari and Chrome) can open "mailto" links in a new tab in FF (which is my default browser, and used for mailto links) just fine! Here is an example of the URL that I see in a new FF tab opened via Chome: https://mail.google.com/mail/u/0/?fs=1&tf=cm&source=mailto&su=Cover+of+the+River+Journal&to=Steve+Mones%3Cstevenmones@optonline.net%3E Any help would be appreciated. - Thanks, Jim

Running Firefox 98.0.2 (64-bit) Mac OS Monterey 12.2.1 (21D62)

Many websites are not loading at all or taking many minutes to load (bankofamerica.com, maps.google.com, etc.) Maps.google.com does not even load on Firefox.

Usually indicates 'waiting for fonts.google.' in the lower left hand corner, but site never loads. This is happening more frequently, on more and more websites.

Google Chrome has 0 issues loading the same websites. Firefox specific issue independent of ISP. Tried restarting, updating, etc. No luck.

I've been utilizing the security protocol app DUO for work purposes for the last year with Firefox, no issues. I just recently updated to 105.0.1 and received the following error message when my DUO was prompted:

• "We're sorry, access is not allowed with Firefox due to security concerns." - with a sad face.

It then shows me a list of compatible browsers and FF being the only one not allowed to use the DUO authentication. I've attempted to clear my browsers cache, fire up FF once more only to arrive at the same messaging. I've uploaded a screenshot of what I ran into.

This has to be some sort of error as I've been utilizing FF and DUO together successfully with no issues over the last year.

Any help is greatly appreciated.

I am using firefox v104 on linux mint. This problem happened this evening. Every tab i open shows the same error.

I tried the solutions suggested in other similar forum posts like >safemode (tabs still crashed) >driver update (my drivers are up to date as far i can tell) >deleting cache and reinstalling firefox (tabs crash). I took a backup of my bookmarks and extensions as suggeated in another forum post. > one youtube video (https://youtu.be/F9VaXwSB_po) suggested toggling media.cubeb.sandbox in the config section. The tabs started loading after that but it wasnt that useful as i wasnt able to get any videos to play in the browser.

Also, i don't really know if the issue is related, but chrome tabs were also not loading or responding ('Page unresponsive' error).

Please help. Thank you :)

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

Hi everyone,

I have the problem in the Subject line. FF sucks about 500 MB to be run, on top of which it takes 500 MB per tab, and that makes it impossible to run a research on my 8 GB Mac. Yesterday I was looking for a lamp and had no more than 7 tabs open, 3 of which were largely text, 2 were online shops, and 1-2 were websites with pictures. No Facebook or social media, no YouTube. FF froze, made the whole Mac freeze (well, Mac is garbage nowadays but let's leave that out of this topic), and I had to wait MINUTES before I could close it, because the computer was nonreactive.

When I check online, I see people being like "why can't it manage more than 50 tabs?". 50?!?! My computer dies with a maximum of 10 when it's only text websites!

So, I guess there's something wrong with this.

- I don't have many extensions (SimilarWeb, VPN, and Flash Player), I always use incognito so I can't use the plugin that allows me to use several accounts at the same time, so I can't see what's messing with my Mac. - The Activity Monitor (pretty much Task Manager on Windows) shows "FirefoxCP Isolated Web Content" for each tab, could that have anything to do with my problem? - CPU usage is very low, some 0.5 to 10% max during heavy use. - I seem to remember I used to have dozens of tabs open in the past, although I can't be sure. Is this a recent problem?

I really hope there's a way to solve this, because now I always fear that opening FF while on a Zoom meeting might freeze the whole thing.

Thanks to anyone who might want to shed some light on this big problem.

Screenshots: RAM and CPU usage with 2 tabs open. Two, taking more than 1 GB of RAM and about 250 threads in total? While using 0.2% of the CPU? I'm lost

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:
