Firefox Support Forum

In history, prior visits to pages are hidden. The information appears to be retained. How can that filter be removed so all visits are visible? My goal is a list of URLs visited sorted chronologically.

Firefox Monitor has a limit on the number of monitored email addresses (15). However, I use the "+" symbol to register on sites - just to determine which site caused the leak. That is, email@mail.com and email+forum@mail.com are the same email address. I have hundreds of such modified addresses. However, the Firefox Monitor allows you to track only 15 of them.

Is it possible to remove the limit on the number of addresses served, or make the FM perceive email@mail.com and email+forum@mail.com (etc.) as one address?

So I want to know if there's a feature that can perform similar perfromances as the chrome's bookmark will do, so what i want is that to have a bookmark below the address bar.

Hello,

Does Firefox support Office 365 online? I opened a Word document on Dropbox website and I got a message that office is not supported in this web browser. My computer has Windows 10 OS and I used Mozilla Firefox Developer as well as Mozilla Firefox. A colleague of mine has the same issue while using macOS Mojave 10.14.6 and Mozilla Firefox.

BTW I have Dark Reader plug-in enabled in my browser, that's why the picture is in reversed colours. It doesn't affect the problem described.

Thanks.

So I have been Firefox Developer Edition on three different devices for the past year and just a few days ago on one of my devices, Firefox would not keep my theme settings, extensions, or accept my master password, so I closed Firefox. But that didn't help and since i needed to reboot my system anyway, I did a reboot and when I logged back on and tried to open Firefox it gave me an XUL Runner error saying that 75.0 is not compatible with min version >=74.0. So I uninstalled FDE and then re-downloaded it, reinstalled 75.0 since I do believe that the update to 75.0 had hung up on this particular device a week before. So then a day later my other two devices started having issues, so I tried to sign into another Firefox account, that didn't work so I did a reinstall and it seemed fine for a minute until I realized all my passwords/logins/history were gone, so I tried to sync again and then it gave me the message to set my master password, so I tried and kept getting the 'Cannot change master password' error. I have reinstalled twice and create a new Firefox account, tried to sign into an older one. I know someone will say just use the regular Firefox, but I use the FDE because my other Firefox browser is set with a work account that I keep to backup user data at work and I cannot use for my personal device. Any ideas?

Warum erhalte ich bei Updates "BETA-Versionen", ohne dass ich diesen "Service" gewählt habe? Was ist mein "Vorteil"? Ich denke, dass Beta-Versionen per se nicht ausgereift und daher lückenhaft bzw. noch fehlerbehaftet sind. Wie kann ich diesen Status wieder loswerden?

Firefox is my favourite browser, but it has some problems. Although the team managed to fix memory leak issues with BigInt in js, but the performance is 3x slower than NodeJS compared to the latest spidermonkey (75.0b6).

To test out, I have created a simple pi calculator (open source), the website is: http://picalc.rf.gd/

The source code can be found on github, or just by clicking the "View Page Source". It seems impossible to get past 4,000 digits of Pi in firefox but in chromium I can calculate about 10,000 digits in the time firefox does 4,000 digits.

Previously, in the earlier versions (73 I guess), the memory went all the way up to 4 gigabytes while trying to calculate 5,000 digits, it's now (my current firefox version is 75.0b4, developer edition).

For the benchmarks, I have also tried NodeJS and Firefox's Spidermonkey.

screen says: The address wasn't understood.

Foxfire doesn't now how to open this address, because one of the following protocols (rtsp) isn't associated with any programs or is not allowed in this context.

You might need to install other software to open this address.

Before, Firefox would remember where I had saved a file based on the domain. So it would remember that things I download from my banking sites go in the user/finance folder, and things I downloaded from board game sites go in the user/games folder. It stopped doing that and now it defaults to whatever the last used download location was, regardless of the download domain.

How can I get it to revert to the previous behavior? It was very handy for it to remember that a file downloaded from the site http://foo.com/ went in the user/foo folder...

hello, in url-bar i type next: asmkru.dev.blog-eis.ru. But i can't go to this site. Tested by Chrome, Mozilla (normal) it's okay, but this problem by Mozilla DE

Issue: Cannot play Amazon Music Unlimited.

Platform: Nvidia Jetson Nano

Processor: ARMv8 Processor rev 1 (v8l) × 4

OS: Ubuntu 18.04 LTS

Browser: Firefox for Ubuntu version 75.0b11 (64-bit)

Description: When I log into amazon.com, I can play music excerpts but when I go to Amazon Music, I get the following error: Playback disabled – Please enable playback settings for your browser.

I saw on an Amazon forum (https://www.amazonforum.com/s/question/0D54P00006zSzZVSA0/linuxplayback-disabled-message-in-firefox) that Amazon Music playback is not supported if you are using a Linux computer. Customers using other operating systems (including Linux, Chrome OS, Windows versions older than Windows 7 and versions of OSX below 10.9) can download purchased music directly through their computer's web browser.

However I hear other people are playing other Amazon Prime content using Linux so I suspect you can make it work if you get Widevine.

Reading the forums, I think my issue is that I need Widevine Digital Rights Management.

One forum (https://support.mozilla.org/en-US/kb/enable-drm) said that Widevine would be installed (Firefox downloads and enables the Google Widevine CDM on demand, with user permission, to give users a smooth experience on sites that require DRM). They also have instructions on where to enable it in the Add-ons Manager Plugins panel, ellipsis icon next to Widevine Content Decryption Module provided by Google Inc.

On the Add-ons Manager Plugins panel I don’t have Widevine listed. I see “OpenH264” and “Shockwave flash” but I do not see “Widevine Content Decryption Module provided by Google”.

It also said that you can always turn DRM playback on again by opening the Firefox Preferences General panel and, under “Digital Rights Management (DRM) Content”, putting a check mark next to “Play DRM-controlled content”. I don’t have “Digital Rights Management (DRM) Content” listed on the General panel.

I assumed that Widevine didn’t install on demand. So I found another forum that explained how to download the zip file from Google. I did the following steps to get the latest file and I put it in the plugins folder.

sudo wget https://dl.google.com/widevine-cdm/1.4.9.1088-linux-x64.zip

sudo unzip 1.4.9.1088-linux-x64.zip

sudo mv libwidevinecdm.so /usr/lib/firefox-addons/plugins

sudo chmod 644 /usr/lib/firefox-addons/plugins/libwidevinecdm.so

Still it doesn’t appear in my Plugins.

Questions:

   • Do I need Widevine to play Amazon Music Unlimited?
   • If I do, how do I install Widevine?

In mac os x in firefox developer version I always quit Firefox in full screen mode with many or some open tabs. When I open up it again it starts with maximized mode mode instead of full screen mode that I leaved it.

About 4 days ago my Firefox started randomly crashing. This happens for example when I open up a new tab and type something in my normal typing speed. Or sometimes when I switch programs and in the mean time all the windows have crashed. Usually the whole Firefox just freezes, becomes unresponsive, and I have to manually end the task, but a few times it has crashed faster than I can blink. No other program in my PC crashes, so I doubt it has anything to do with hardware.

I have done a clean install for the fourth time, every time changing something, be it following the tutorial to restarting between uninstalling and reinstalling. I got some kind of crash report, which I will paste below.

I could not find a person with a similar issue. This is really irritating, as during the lockdown I need to work at home, but I can not use my preferred browser to do tasks. Maybe it has something to do with Facebook Container, which I installed after it was announced to me.

Thank you

Two or three weeks ago I was able to get to my router settings with Firefox. I tried to get to the "routerlogin.net" page yesterday and was redirected to another Netgear page indicating that some web browsers were "caching" the page and that is why I couldn't open the page. I uninstalled and then reinstalled Firefox and it still has the same problem. I tried Microsoft Edge...same problem. Yesterday I installed Google Chrome and was able to easily access my router. I prefer to use Firefox as I have been for several years. How can I fix the problem?

This is a LAN wired connection to an on site router that OF COURSE does NOT have any built in SSL support. FireFox now prevents my Netgear recommended connection method from working by forcing a HTTPS URL when attempting to connect to my router. If I manually correct the HTTPS and make it HTTP, FireFox just forces it back to HTTPS when I enter it. Yes, I know how to use the direct IP, but I would like my router to work as Netgear intended. (like it used too a few FireFox versions ago). YOU broke routerlogin.net.

I have Googled everything I can. Tried it all. I have clicked on the Lock and the circle with the arrow. Went to the settings. used about:config and someone said about:flags ( that doesn't even work )

I can't get the darn thing to work. It's been over and hour and you know nothing should be that hard to do. This is way too complicated for all that time just to turn on a mic. I can't get it to work in Google Docs Voice typing. Anyone?

From Firefox version 47+ icons have been changed to have outline style. I couldn't figure out how I could replace or revert them to the good old colorful ones. I know this is the trend nowadays but wireframe icons still look unprofessional and are hardly recognizable at first. I want colored icons with shades and gradients. For back/forward, refresh and home navigation buttons. For Downloads button. For the show sidebars button.

Where can I get these icons? Should I extract them from a previous version or are they still there in new versions?

How can I change them? Do I need to overwrite files in the installation folder or is there a configuration option?

In FF If I type in WhatIsMyBrowser.com, type I see "No javascript is not Enabled". I then type in 'about:config' in the address bar and see that javascript.enabled is true...but if I close/reopen FF, it reverts to "not Enabled". Is there a simple 4-5 step method of enabling javascript so that it stays enabled? Thank you.
