Firefox supportforum

I've been having frequent trouble starting Firefox for the past month or so.

Sometimes I get the Windows error message that Firefox crashed and asks me to restart, check for problems, or debug the application.

Sometimes Firefox will open on a "New Tab" and fail to load my default home page (http://localhost/default.html). A dot on the left side of the tab cycles back and forth continually.

I'm using Windows 7 Home Edition with IIS installed.

Thank you.

I have problems with multiple sites that claim that third-party cookies are blocked and do not work even though though the Enhanced Tracking Protection is disabled for the site (the shield icon is grey and striked-through). In particular it is teams.microsoft.com and Instapaper (their saving bookmarklet sends me always to a site reading "enable unrestricted third-party cookie access for www.instapaper.com" - though this might be a different issue than Teams).

I have read https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop?redirectslug=enable-and-disable-cookies-website-preferences&redirectlocale=en-US#w_how-to-tell-when-firefox-is-protecting-you and https://support.mozilla.org/en-US/kb/websites-say-cookies-are-blocked-unblock-them (trying even to "forget" the teams website; not doing the full wipe out of everything).

How to troubleshoot / fix this? I am a technical person so I can dig into it if just somebody points me in the right direction...

Thank you!

Dear all,

how can I tell whether my version of Firefox already has received the shipment of Enhanced Tracking Protection 2.0? Is there any notation somewhere? (I searched for it, but did not find anything, neither in the ETP settings or in the Protections Dashboard, nor in about:config.)

Please advice how to find out. Thank you!

Print preview shows a single page, which is totally appropriate for the content. It says "1 of 1" at the bottom. Click the print button, and it prints 2 pages. (No changes done to formatting, selected printer or anything else.) The second page is completely unnecessary and consists only of a header line at the top, identical to the first page, and a footer at the bottom, which says "2 of 2" and the date and time.

'Print preview is NOT a preview' of what it actually is going to print and reformats the document without warning or permission.

Hi,

this is a weird issue with "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0": The contents of Dokuwiki codeblocks disappears when clicking in the block, not only on self-created pages, but also here: https://www.dokuwiki.org/plugin:code2

The problem exists only with code blocks in the lower half of larger Dokuwiki pages, therefor might be a memory/cache issue.

Reproducible as follows: - on different machines with FF 68 - 78. - in Safe Mode - with a new empty FF profile

Cannot be reproduced with other browsers (Chrome).

I am quite cueless so far. Any help appreciated.

Hello good people, This is rather a request for advice than an issue report. I' ve learned about the facebook container add-on and wanted to know if there is a need for it if someone was making sure to exclusively open facebook.com in its own profile. Say you set up a profile(from about:profiles) namely "BIg Brothers" for notorious trackers like google, facebook , twitter etc so they can perpetually track each other with simple rules to observe like : - Never open an external(shared) link - Never access any other website through that profile.

Is there a particular feature the add-on is bringing up that the native interface is missing ? The other reason is add-ons are great but they tend to bloat the system impeding the browsing experience. I am the kind of guy who opens 7 concurrent tabs each running heavy js code so the lighter the better.

Thank you in advance,

Dom

Firefox Developer 80.0b7 (64-bit) Mac Catalina V 10.15.5

I've tried using the userChrome.css file to change the background color for the active tab. create chrome folder in profile folder create userChrome.css file and add: .tab-background[selected="true"] {

 background-color: #ffffff !important;
 background-image: none !important;

} Set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE Reboot mac This does not take affect and the userChrome.css file is not visible in Style Editor.

What am I doing wrong? thanks Milton

Not sure when this started or why it is happening. I have double checked that my settings have Google search set as my default search engine. Instead, Yahoo Search keeps popping up.

How can I stop this?

Thank you!

I have had to change the Search Engine back multiple multiple times after changing to DuckDuckGo and removing the others!

Why does the system Windows 10, if that is the culprit continue to change it away from DDGo? I removed the Microsoft Edge File from my Computer. It used to be the one that replaced it!

Hello, I want to be able to search directly from Google, Bing, etc. when I am in a private window. Computer will search from the address bar only when initially bringing up a private window. I type in Google.com, Bing.com, etc. in the address bar & I then can search from their search box.

Some website are opening fine but some are not, showing Secure Connection Failed PR_END_OF_FILE_ERROR. Even Google, Youtube are also showing same error page. I have tried every probable solution from internet. Even I have tried to open browser in Linux system installed in my pc and found same issue. This problem is coming from few weeks, previously it was fully ok.

Please help me to rid out of this.

Hello,

I reinstalled windows on my laptop, and when i installed firefox and signed in with my account, none of the old settings, bookmerks, singins etc got synced. I downloaded newest version from website. Does anybody have a solution to this problem?

Thanks!

I've read this article: https://support.mozilla.org/en-US/kb/push-notifications-firefox

It tells me how to disable new notification requests, however when I go to website, the icon still appears. The icon still wiggles. I want to remove this ENTIRELY. Under no circumstances do I ever want to know anything about any website with notifications. It should be 100% removed because it is trash feature from trash companies.

When I save a pdf-file it is automatically converted into a firefox html dokument. Also all my old safed pdf-files are converted. What does happen? And how can I stop it? I'm not able to safe my scans as pdf anymore.

Add-ons in version 79 are not holding their settings.

No script, foxclocks in particular.

Every time I log out & log back in later I have to reset everything.

I don't have time to be resetting the add-ons all the time.

I was using Sync thinking it would be easier but I found it to screw things up worse so I logged out of FF acct..

Is anyone else having issues with add-ons holding their settings in ver. 79.0?
