Diễn đàn hỗ trợ Firefox

Google won't let me sign in and here is what they say: "The browser you're using doesn't support JavaScript, or has JavaScript turned off.

To keep your Google Account secure, try signing in on a browser that has JavaScript turned on."

I have recently updated to the latest version of Firefox and seemed to have no problem yesterday. What do I do now?

I'm using Firefox 67.0 under MX Linux. My monitor is 25" with a resolution of 1920x1200. With this resolution, the text and icons in Firefox Menu and Toolbars are tiny and almost impossible to read. The Thunderbird add-on Theme and Font Size Changer works reasonably well for Thunderbird, so is there a corresponding add-on for Firefox?

I know that Firefox is largely developed by people who are volunteers, but it seems that a tool, as part of the basic Firefox program, should be available to make these changes without installing add-ons or modifying the code manually. Almost everyone needs to be able to tweak these things at one time or another.

Earlier today I tried to full screen youtube and It wouldn't work. I saw some suggestions on here saying delete cookies so I did and now it full screens, however the video is partway down the screen and above it is an empty white box. I've tried restarting in safe mode and deleting cookies again and neither of those worked. i'm having no issues in other browsers so I have no idea what could be causing it.

My plugin(the normal one which is already installed at the beginning) for DRM media isnt working since I deactivated it one or two times and then reactivated it. The Problem? You see it on the screenshot its still not active and I cant play DRM media.

Anyway I dont really need it if there is another plugin for playing DRM content and if there is one I might prefer it because I dont like google that much.

So please tell me how to fix it(maby without reinstalling firefox) or tell me which other plugin I could use instead of it.

(I already tried to: restart firefox; my PC, update the plugin. I will check if it updates if I run it as a admin but I dont think so)

Menus on Firefox itself are displaying in my native language, when I've set them to English.

I've uninstalled all language packs that aren't English, even removed other languages in Windows settings to make sure Firefox displays menus in the language I want, but none of it worked. Already checked about:config and removed any traces of other languages. The settings page itself and other Mozilla webpages are all displaying in the correct language, but the application itself is not.

It started doing this after the most recent update, was working fine before. Only explanation is Firefox is using my location to set a language and completely ignoring my language settings. Should I just wait for it to be fixed?

Hi all. I rely on quick opening of hyperlinks from Windows 10 Mail app to answer Microsoft Community forums questions in FIrefox, which is set as my default Browser, and has defaults set for http and https protocols. When I upgraded to both Windows 10 Version 1809 and later to 1903, Firefox stopped opening on it's own and instead opens a new tab every time I click the link in the background. I have to click it's taskbar shortcut to open it.

These hotlinks still work correctly in Edge and CHrome but I need Firefox for managing my Bookmarks collection to easily drag them into help posts which isn't easily done in the other browsers.

Appreciate any help.

I can hover over the menu and it will display my submenus; however when I move my mouse in an attempt to select something from that submenu, the submenu disappears. Never able to select anything within the menu. I have tried running in Safe Mode, didn't resolve. This started the end of May 2019. There were no changes made to the website.

So a while back, like many people, I encountered the issue where I downloaded the cutting-edge Firefox in an attempt to get my extensions back during the failure. Then I realized that none of my stuff carried over, and I panicked to re-install the original to get my stuff back.

(To clarify, "stuff" encompasses history, previous sessions, cookies, saved login credentials, and the like. My sessions are...quite large, admittedly, so I crash often.)

So tonight, it crashed again while I was trying to respond to someone on a chat client. I hit restore previous session as normal. Then the update window showed. No harm done there.

Except then it gave me the dead basic, on-install new tab screen. Checking revealed no history, no cookies or password retained, and an inability to rez my previous session.

As a uni student during summer with a lot to book, this is a major issue.

And while I have attempted to look for Old Firefox Files, they remain elusive.

Fair to note: I use Windows 10 on a bone-average Lenovo laptop.

I have noticed a couple of times recently that when I try to Bookmark All Tabs (I usually use Ctrl+Shift+D) it missed some. This may be because I Have been wanting to do it to:

- Open all tabs from Synced Tabs, then bookmark all tabs (because FF Beta for Android has no way to bookmark all tabs (that I can find))

- Reopen tabs I had just sent to OneTab, then bookmark all tabs

Maybe I am hitting Ctrl+Shift+D too soon after I have opened all the tabs. I have been waiting a few seconds to see that the tabs are definitely open, but especially if there are a lot of tabs I want to simply save as bookmarks, and get on with something else, I don't want to have to wait for every page to fully load - that could take ages and how will I know without eyballing everyone. (When I've only just sent them to OneTab, then reopened, why are they not cached but that's a different issue.)

Recently I have been saving all bookmarks, then counting the open tabs vs the new bookmarks. This is a dumb thing to have to do manually.

Presumably the reason it is failing to catch all is due to them not having yet loaded fully or something.

Ideally this can be fixed, but at least if I know what FF needs to successfully bookmark all open tabs (which it does do sometimes even before every single one has fully loaded), I can work around that functional shortcoming.

I'm sharing data, but this has happened on another PC too - much higher spec than this one I'm using today.

Hello, I'm using a macbook pro laptop that I just upgraded to Mojave 10.14.5. After my update to Mojave, FF worked just find. Loaded my home page and everything worked as expected. Then today I updated to FF 67.0. Since then my home page comes up as a blank tab. I checked my preferences and my home page website is still listed. So, I deleted it and redid it. Close FF and then reopened. Same thing, blank tab. So, I'm hoping someone else has had this problem and has a solution. Oh, I did find out, if I click on the home button, my home page loads in the blank tab.

Thanks in advance!

If I select "Save files to" all downloads are successful, but if the option is set to "Always ask me where to save files" Firefox will freeze when I try to select a location for the file or when Save is selected. I have tried the following without success: 1) Start Firefox in Safe Mode (sometimes downloads complete, sometimes it freezes) 2) Refresh Firefox (sometimes downloads complete, sometimes it freezes) 3) Create a new clean Profile (sometimes downloads complete, sometimes it freezes) 4) Turn Hardware Acceleration off (does not help) 5 Disabling Shockwave Flash doe not help. No Crash Report is generated since Firefox freezes with the message "Firefox is not responding." I do not experience this problem in Chrome. The freeze usually happens as soon as I select "Save File" but sometimes as late as when the download starts. I would appreciate any suggestions as I am out of ideas and getting very frustrated.

Just updated to latest Firefox on 5/23 (win 7 x64). Started getting an error 'nvcuda.dll is missing'. Not even using a nvidia graphics card!

Not much else to say. Error window pops up at different times. Usually soon after starting, sometimes repeatedly, others just a single time. Only thing updated on my system yesterday (5/23/19) just before the errors started was Firefox 67.0 64x and Mozilla Maintenance Service. I use the system every day and seems to me the FF update must be the culprit in some way.

Have an AMD HD 7900 3GB video card, not nvidia, if that makes a difference.

Accidentally touched a porn ad, after I touched it I could close firefox, the ad brought me to another page and kept me from closing out so I just shut down my computer. Then I logged back on and uninstalled/reinstalled firefox.

Is this enough or is there more to it?

here' a link to the ad - go to at your own risk [Unneeded link removed by moderator.]

As above. FF installed the update despite the checked option to NOT install automatically. NO "old firefox" folder was created-anywhere. No other profile is present that has the old data. My adult daughter's grad school laptop. Years of bookmarks, logins and I do not know what all ARE GONE!! I allowed FF to download but NOT INSTALL-since it was not my machine and I wanted to avert any disaster (I, in fact, looked at the options first, to make sure) NOW WHAT?? Is that is a bug?? Why was there no "old FF" created? Why did it install regardless of instructions to the contrary. Is there some other place to look? She does not seem to have any automatic backups for FF profiles.

Hi,

I was aware of the recent issues as first reported back on the 3rd May regarding 'Add-ons disabled or failing to install in Firefox' (https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/comment-page-5/) in which workarounds were offered or users were advised to update to the latest version. I myself am using the latest version 67.0. I can see all my installed add-ons and can even update and install them where required, but I cannot seem to install any new add-ons at all.

I have included two screenshots showing that I am using the latest version and the second which does not show the usual 'Install add-on' but instead shows the button 'Only with firefox, get firefox now, even though I have firefox installed.

Any help would be appreciated. Thank you in advance!
