Diễn đàn hỗ trợ Firefox

Everytime I try to open a tab on my Firefox window, it loads for a second before a blank screen saying that my tab has crashed. The only times I can open a new tab is on a private window.

I'd like to turn off the recommended articles that I see when opening new tabs. I find them to be quite bothersome, and the link pocket provides to learn more about this features a nonexistent article on how to disable these recommendations. Could you help me disable these?

This is the procedure I followed:

Close firefox

Copy previous.jsonlz4 file to the main level in the profile

It has all the tabs i used to have in it because I made a backup a few days ago

Rename the file to sessionstore.jsonlz4

restart firefox

I get the same single tab I had before i did this

when i go to history tabs, all that is there is the single tab i currently have

Appreciate your help/gary

I used System Restore in Windows because I lost my Search Engine in Firefox and it didn't exist in "Customize Toolbar" option. I researched how to get the Search Engine back but nothing worked. I thought System Restore would solve the problem. Now I can't restore my previous Firefox session. And I can't find a sessionstore.jsonlz4 file. I read you have to rename a file in sessionstore-backups folder to sessionstore.jsonlz4 but I don't know which file to rename. I also read you can restore a recent upgrade.jsonlz4 but that is dated 3/5/24. I loaded previous.jsonlz4 file using the Scrounger tool but that didn't restore the session I had. (The previous.jsonlz4 file is dated 3/22/24 about 45 minutes ago.) I want to restore the session I was using earlier in the day. And "Restore Session" option has disappeared from the Firefox History dropdown menu. I tried the "Restore Firefox" option but that didn't help anything and it made my dropdown menus disappear. I have no idea how to get the session back that I was using earlier in the day.

I have pinned various shortcuts in the New tab to link to websites I frequently use. I use two different laptops and both are configured the same. However the New tab randomly clears the pinned shortcuts. I have attached two screenshots illustrating the changes.

I'm not aware of anything I do that caused the shortcuts to be deleted. When they are pinned I think they should be there permanently.

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

Hello,

I am wondering how to remove the web icons/favicon from tabs (and windows if possible) for specific websites, but not all websites. I know you can hide all favicons using 'userChrome.css' and the code:

.tabbrowser-tab .tab-icon-image { display: none !important; }

Is there any way to configure this to block just a site like Wikipedia, without blocking everything else?

Thanks.

Here the scenario that presents the issue that I'm curious about.

I go to a lot of sports websites to check game times, scores, box score statistics, etc.

While at pages listing the scores of multiple games that are still being played (in-progress), there's an option to click a link on any individual game to see per-player stats about their performance so far in that game, etc.

So, when I click a right-click a link and select to open it in a new tab, fine, it opens okay, no problem there.

However, within the page of the newly opened tab, there is usually a right sidebar column, that is mostly a series of ads and links to related content, yet, there's always at least 1 (and sometimes 2-3,etc) that have embedded video highlight reels in players embedded directly into the page that automatically begin playing when the page/tab loads. It may take a few seconds, maybe up to 30 seconds, but it will eventually start. And, as you probably can guess, yes, of course you have to sit thru a 30-second ad before the real content.

These are little sidebar embedded video players on my 27" 4K screen are no more than a few square inches, with tiny little control buttons, such as pause, volume sliders, etc, the usual array, and a "[+]" expand-icon to expand the player size to full-screen.

So therein lies the nuisance. And it is really annoying. When the tab opens, that little highlights-reel video player is off to the side, very small, barely noticeable to begin with, and at first page load, usually SILENT. But that doesn't mean it's muted, it's not- it just hasn't fully loaded yet and self-started began playing YET.

And then when it finally does, the volume is usually at a default setting of MAXIMUM. And it is LOUD.

It's a pain in the neck that anytime I click a link at any of these kinds of sites by major sports networks that over time you learn to expect that the page is gonna get audio-hijacked whether or not the user is even remotely interested in that content (way over there in that little inky-dinky player on the right), and it just absolutely RUINS the user-experience overall IMHO.

I'm looking for an ADD-ON / EXTENSION that remedies this, ...or-- asking any of you developers who may be reading this to take this post VERY SERIOUSLY. I absolutely can't believe I'm the only user P.O.'d with this horrible "SNAFU" with major sports networks websites. To call it an "inconvenience" is the understatement of the century.

Just to be clear, ad-block has absolutely no effect (ZERO) on this. Cookies ? I'm using Privazer in addition to Firefox's own Privacy & Security settings and built-in cookie cleaning capabilities. And I have used that tandem for years, with remarkably fantastic results, no complaint there, everything works great as far as that is concerned. Except of course the issue of this post/inquiry - this problem doesn't get fixed by clearing cookies or caches, it's apparently loaded & controlled at the server-side, so I'm looking for a way to over-ride that by the client-side by having new tabs open with volume muted as default page-load value (if such a thing is possible).

Also, the above scenario, is my most frequently encountered PERSONALLY, however this issue happens also at quite a number of other website pages where sidebar video content is regularly displayed such as tabloid/ journalism websites, product review websites, and the list goes on and on.....

Getting back to the title of this post ::: "" Is there an add-on that enables when clicked links are opened in new tabs ---> THAT TAB's volume ALREADY muted ? "" .... if there already is an option for this in firefox open new tabs settings please remind me where to find it..... because I am pulling my hair out over this... thanks all.

Version last update :: Firefox Version 112.0.2 (64-bit) Operating System :: Windows 10 Pro 64-bit | Version 22H2 | (OS Build - 19045.4239) Misc Info :: i7-3540M CPU @ 3.00 GHz | 8 GB RAM | Dell Latitude

Hi I read these articles and they doesnt help to resolve the problem https://support.mozilla.org/en-US/questions/1349609 https://support.mozilla.org/bm/questions/1206172 https://www.reddit.com/r/firefox/comments/ip88y7/firefox_is_preventing_windows_10_from/?rdt=53488

Problem: I have Win10. Firefox 107. I have noticed that if I have opened only regular/textual web pages in my tabs like news/articles then PC goes to sleep after specified time of inactivity. But if I open in the one tab some media content like videoclip/animation/movies and put media content on pause then PC doesnt go to sleep after specified time. PC goes to sleep only by manual command (Start>Sleep). Even If I close the tab with media content PC doesnt go to sleep after specified time. I should or totally close the browser with all opened tabs or manually select Start>Sleep.

Could you help to resolve this issue ?

On the screenshots are shown that some of firefox processes couldn't stop making some activity, every second they make some web request or disk operation. May be this is reason why PC cant go to sleep. But again, this is happen only or some media content is put on pause or some tab with media content has been closed.

Tabs always start in mute mode. I can turn it on by pressing speaker logo in the tab. The problem is when I shift to a new tab, the previous tab mutes automatically. For example: I listen to YouTube music and want to check my mail. When I shift focus to the new tab the first mutes it self. Any suggestions please. Sincerely Oscar.

I was running 8 Windows with about 12 tabs per Window. AND I had it set to Continue Where You Left Off, so that each time I closed and launched FireFox, ALL Windows with ALL Tabs would open. No problem. Easy.

This morning, Firefox crashed and LOST EVERYTHING. Why did it happen? And how do I get them back?

Jev

I understand that as outlined [https://support.mozilla.org/en-US/kb/pinned-tabs-keep-favorite-websites-o...], pinned tabs aren't designed to be closed with ctrl+w.

I would still like that behavior though, is there a way to either assign a shortcut to that funktionality (one that I would just also map to ctrl+w) or remove the protection altogether?

I know that you can change a lot of thing sin about:config, so I have hopes that there might be something for this as well. Alternatively, do you maybe know of a plugin to allow this?

What wouldn't be useful are solutions requiring additional actions (Just unpin first, just use MMB, here is a plugin to give you a shortcut to unpin etc).

If it is just not possible right now, is it likely to become an option later on? If not it seems like a useful feature request. I understand that the current default behavior makes sense, but part of what makes firefox great and different is its customizability, so having what I want be a hidden about:config toggle feels very on brand (or even a setting in the normal settings menue - but even there it might be too niche and cause bloat).

Hi, Since few weeks ago, firefox never restores my previous tabs/session (I lost a year worth of tabs..), no matter what/how I tried, it keeps starting with a clean session, not even the history in there. I tried: Deleting profile, creating a new one Resetting Firefox Fully delete FF and delete the profile folder Heck, I even used librewolf, and even FF on linux and also Librewolf, same issue!!

I notice this happen once I enable the sync (login to my account), there's no setting in my account says to never restore the session or something similar.

How to solve it?! I need to have the tabs open again..
