Diễn đàn hỗ trợ Firefox

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

A website I use to move money - getting message telling me cookies is blocking 3rd party cookies. and I need to enable 3rd party cookies. I go to settings in firefox and for the information to set settings to enable cookies 3rd party they do not work. They tell me to check and uncheck boxes that I do not even have for setttings. I never had this problem before until Jan. of 2022. I have to use a different browser to get to the website and complete my task. There is something in the Firefox browser or they made changes/updates. Need step by step instructions. NEED TO TALK TO SOMEONE.

I'm running Windows 8.1 64bit, and a 64bit install of Firefox

Without exception, any time I try to update Firefox or close the program, it balloons its resource usage and then crashes.

Every. Single. Time.

I have submitted several crash reports over the years. What is happening and how do I stop it?

Also, why does it clear my clipboard? I Ctrl-C'd a url before closing it just now, and after it crashed and a restarted it, Ctrl-V was empty.

Please, why would you remove FVD Speed dial without first giving a warning so users can download their latest websites they have stored on it. that S__t is F______d up. What The F___ . some of those sites I had saved were hard to find the first damn time and now the whole set is f____ ing gone. I did not GIVE A DAMN if they shared data. I want my damn FVD Speed dial back or access to it to save my stuff first.

I find it totally unacceptable that you removed the tool I use THE MOST with out any opportunity save my tabs to export so I can still have them.

That arbitrary do it with no warning s__t is rude as f__c.

I have ongoing Adblock Plus and Ghostery, but since the latest update to Firefox 95, I have seen a significant increase in the numbers of Ads on internet news sites (TheGatewayPundit.com, ZeroHedge.com, etc.). I've have also experienced for the first time, a request to sign up in order to continue to view something (Fox News; Political Cartoons). Is this a result of the Firefox update or have the advertisements managed to overcome Ad blocking software? Is there a fix that you can suggest? Thank you for taking the time to read and respond.

I'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

Apologies for asking this here, but I've done the Google and can't find an answer.

Background: I keep 2-3 Firefox versions and profiles on my computer. The software is in, for example, directories FFox82, FFox84, FFox86 The profiles are in, for example, directories Firefox82, Firefox84, Firefox86 (The software and profiles are on different drives.)

When I do an upgrade, I copy the newest software to a new directory and rename it (e.g., FFox92 - so now there are 4 sw directories) Then I copy the newest profile directory and give it a corresponding name (e.g., Firefox92 - so now there are 4 profile directories). I install the new version to its directory and thenlaunch with a -p option. Then I create a new profile and point it to the corresponding folder. Then I launch the new version with the -p option pointing to the new profile directory.

This has worked for decades.

But I just tried it with Firefox 90 and Firefox 92 and NO GO. It acts as if I've never used Firefox before. No apps, no toolbars, no bookmarks, nothing.

What is going on? Am I stuck on Firefox86 for the rest of the century?

And, please, don't tell me how wonderful these new versions are and I should simply accept the change. I have a virtual lifetime invested in the toolbars, extensions and bookmarks on my computer.

I simply want to know if there is a fix and, if so, what it is.

Hey, All of the saved logins and passwords are gone while the bookmarks remain.

I noticed that logins and passwords disappeared after the computer turned off unexpectedly due to low battery and unstable power connection couple times in a few minute interval.

How do I get back logins and passwords?

i opened firefox (v.95) and tried opening up my email and found that all my saved passwords were gone from firefox on my computer. it said i should crate a firefox account to get my logins back so i did and i still could not access any of my web logins. so i searched the help pages. opened up my profile n made a backup of my key3, key4, n loginjson files, downloaded v.91 firefox esr and copied my key3 file into a new profile.

so i still dont have my web logins ... n now i have an outdated version of firefox with none of my bookmarks either. im sick of troubleshooting n my wifi is almost out for the month.

how do i get my web logins and bookmarks back so i dont have to spend hundreds of hours recreating them?

As with above title, whenever a video is next in queue and starts, the tab crashes. Also, randomly, if a website has an embedded video player, it will crash usually.

Hi,

I'd like to use keyboard media keys (play/pause, prev, next) to control Spotify web player and Youtube but they don't work. The option is enabled. I'm using Firefox 88.0 on Windows 8.1, so according to this article it should be supported. The keys work on other apps. I've tried in troubleshooting mode as well, no luck. Any ideas?

Firefox is not properly displaying text on brave search results. When this page is displayed in chromium based browsers, text is much thicker and has some fragments in bold. Firefox has thin text and no bold fragments. Text is so thin it is barely visible. Problem only happens on win 8.1. On win 10 page displays normally. I compared win 8.1 firefox fonts settings to pc with win 10 and they are the same so page should be displayed similarly.

This is page on firefox on win 8.1 https://i.postimg.cc/Gt4k0DF6/1.png

This is page on win 10 or on win 8.1 in chromium browsers. https://i.postimg.cc/1XbDyzMX/2.png

Getting sick of FireFox, I want to search from the GOOGLE SEARCH BAR, not the address bar, but the settings don't work you can choose to have the search bar next to the address bar, but it doesn't work, the google search bar doesn't work either, no matter what setting, your search ends up in the address bar, with all the updates, they don't fix crap on here, when someone makes a complaint, FIX THE CRAP, I don't need to ask 100 people why it wont work, just FIX IT!!

I've had this problem for a couple of years already. Not with other browsers and, with the Internet Download Manager extension, I'm usually able to download multimedia content in FF. (That's been my workaround.)

For example, when loading this humble URL ... https://upload.wikimedia.org/wikipedia/commons/transcoded/d/d8/Plattenknistern_record.ogg/Plattenknistern_record.ogg.mp3 ... if I have autoplay enabled, it'll crash right away ("Your tab just crashed"), without autoplay, it'll crash as soon as I hit play. Until a few days ago, no crash report was created under about:crashes, but, after upgrading to 112.0.1, I've finally been able to submit a crash report: bp-203a462b-e949-47b0-90f3-a99760230422

No difference if I create a new user profile and disable add-ons. Disabling hardware acceleration doesn't help either. I can't do without most of my settings and add-ons, so refreshing FF is not an option. I'd sooner try a new install (and then import my profile and reinstall add-ons), but that's laborious and not guaranteed to solve the problem.

(I've submitted this question before, about half a year ago - now archived -, but that didn't go anywhere for lack of crash diagnostics.)

I just got my upgrade from Firefox86 to Firefox90 working, but the tab bar is completely missing.

I still use "old-style" FIrefox. From top to bottom: File/Edit/View menu Search bar Bookmarks Toolbar Tab bar

(yes, I AM old. I've been using Firefox since Version 1 and this particular style works for me, developers be damned.)

The tab bar is completely missing. Firefox knows how many tabs I have open (it warns me when I try to exit) but doesn't show any. The area that the Tab Bar used to occupy is simply empty.

Any ideas on how to fix? (Yes, I have done the Google.)

Hello. Starting yesterday, Firefox has stopped playing audio from every website and even local files. Yes, I read this article and no, the sound is not being muted instead the sound just refuses to play. In the screenshot, it shows that the "play" "mute" and speed option are greyed out. Also, I tried using safe mode and audio still wouldn't play. What should I do?

I didn't ask for this change, and I don't want it. Black on white is hard on my eyes to read.

I've already checked around the forums and nothing that other posters have suggested works to change it back. Yes, I use a custom theme and I'm not going to change it to "white". I didn't make any changes , firefox did.
