Diễn đàn hỗ trợ Firefox

I have run Firefox for years on up to 4 PCs at once, everything has always synced and screens all look the same. Recently one laptop lost the addon extension icons in the Firefox toolbar. They remain on all other installations. I have tried uninstalling Firefox and installing an earlier build, and also the latest Beta build with no luck. All extensions show as installed and activated. I have copied the Profile from another laptop. I have of course done a reset. Any other suggestions?

How can I add a webpage shortcut to the FireFox home page in Windows 10? I just want to simply add a shortcut to a webpage that is currently not on the home page, in spite of having visited it several times. since the automatic adding of visited sites is not consistent (some sites do not show up on the home page no matter how often I visit them while others that I have visited once act like they are pinned, but they are not), I need to be able to add a website shortcut manually, and none of the help articles that I have found successfully do that. at least in my current version of Firefox, which is version 108.0.2 (64-bit).

Tabs, history, bookmarks, basicly anything and everything that was crucial are gone, seemingly after recent update. I had similar problem a couple of month ago and didn't find clear solution back then, but it all got sorted out maybe in couple of days (probably with next update or something?). Well who would've thought i would get screwed like that a second time.

So i can't tell for sure whats caused it or how it got fixed. What i manged to figure out both times this happend is that somehow i have 2 versions of Firefox Profiles judgin by the dates of the cursed updates. So i guess my stuff is still there but i can't acces it.

Also worth mentioning is that both times i've got screwed by updates, my FF shortcuts from Quick Acces pannel stoped working and i needed to drag'n'drop em all over again.

Im at totall loss here, i know the info i've provided is almost nonexistant but if anyone knows whats up i would be greatly apreciative if you could tell how do i fix this and prevent it from happening in the future.

Hello, I am struggling with a bug specific to Firefox (108.0.2) in which I have an XHR Post that is being blocked by dev tools only when a google captcha is selected. Here is the website that the bug is happening on. Per comment suggestions I've added a screen shot of the URL being blocked in dev tools.

My overall goal is to have this form post it's action and post the form data to another endpoint (https://beeceptor.com/console/preferencecenter). I am able to successfully post data to beeceptor with the captcha selected when testing in Chrome, but as stated not Firefox. If the form is submitted without the captcha selected the data is successfully posting to the beeceptor endpoint- this behavior is happening with both Chrome and Firefox which I am sure means something is wrong with my Javascript which can be resolved later.

Looking at the console in Firefox I am consistently seeing a XHR Post blocked to the beeceptor url with captcha selected. I have gone through several iterations of this code to resolve the issue, none of which have successfully worked. After many, many, hours of digging I have done the following to no avail.

• Cleared Cache
• Ran in Safemode then back to regular mode (one article this appeared to fix for a user)
• Ran in Private Browsing
• Adjusted CORS accordingly

There are more items I've attempted that I can't remember off the top of my head.

Any help with this would be greatly appreciated as I have hit a wall.

I am trying to have Firefox show an "X" on every tab as soon as I hover above it. I followed a certain article and implemented this code:

/* Show Tab Close buttons only when hovered */

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {

 visibility: collapse !important;
 opacity: 0 !important;
 transition: all 250ms ease-in-out !important;

}

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]):hover > .tab-stack > .tab-content > .tab-close-button {

 visibility: visible !important;
 opacity: 1 !important;
 transition: all 250ms ease-in-out !important;;

}

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {

 display: -moz-box !important;

}

This code is however not being implemented no matter how many times I restart Firefox. 'toolkit.legacyUserProfileCustomizations.stylesheets' is set to True The location is userChrome.css is '/home/user1/.mozilla/firefox/yqomjsh9.default-release-1672744596809/chrome/userChrome.css'

What could be the issue? I tried adding executable permissions using "chmod" but that did not change anything.

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

Error code: PR_END_OF_FILE_ERROR

I inadvertently switch from the Classic AOL Mail page to their new one but do not know how to switch back. I would very much appreciate any how-to response be in a language that a technologically challenged senior citizen would understand (lol). Thank you.

I had the extension for Dashlane working on Firefox. It looked up and I removed it. Now I cannot locate the Extension when I select Themes and add-ons and search for Dashlane. Any suggestions? Thanks in advance,

I am beginning to be asked by websites to turn-off ad-blocker. Just realized that Firefox has an ad-blocker embedded in its software. When I go to Add-ons & Extensions, Ad-Blocker is not listed so that I can turn it off. Suggestions on finding ad-blocker and having the ability to turn it off and on would be appreciated. Thanks

Is it possible in any way to search or filter history grouped by date range?

Using sidebar history - changing View into By Date or By Date and Site , history is grouped by date (and / or site) as desired. As soon as I enter any search text, view is changed into simple list of pages, not being grouped by date anymore.

Using Library - History I can select date range on left side (Today, Yesterday, Last 7 days, This month...) however as soon as I enter text into Search history textfield on top right position, selected date range is ignored and all visited sites are displayed as a plain list again.

How can I simply filter displayed visited sites when grouped by time by any keyword? (Sidebar is much preferred, because I can directly click-open-see any history site while from library I need to switch between history windows and browser window)

How do I get rid of keybinds or at least change them it's really annoying when I'm working on stuff and i try to close one tab and then i close the entire window by accident by fat fingering shift.

Hello! Since a month I have a strange problem - Firefox wont connect to any Google service - REcaptcha, google-analytics. Any site that uses these services would not load, or loads and waits until connection expires. I tried refreshing Firefox, the uninstalling and re-installing - the problem remains. I do not use any proxy or firewall on my computer. Opera and other browsers do not have this problem. Please, advice.

Hello Firefox! I wanted to understand if there is a way for a user to login to Outlook WEB ACCESS. If you login to OWA on Firefox, is there a capability to have S/MIME active?

I have researched that this is possible on EDGE, and did some research on Google to see if this is common.

Would there be a FAQ or guide on this topic?
