Firefox supportforum

The old PC which I used and uninstalled. (I also disconnected this PC at the account manager.)But others use this and install the firefox again. They didnot need to login my account. When the firefox install and login automatically. Everything of my password and bookmark have been share as well.

Installed Firefox 75 and then 76 on Windows 7 embedded (32 bit) on a thin-client. No errors. When I press the letter "t" on the keyboard it refreshes the page. I have tried this on several input fields on this specific webpage and it has the same outcome. This only happens if I use a lowercase t -- shift-t and T (using caps-lock) does not refresh.

This occurs on a specific page on my internal network. I reproduced this on 3 computers running the same versions of everything. Reinstalled windows and Firefox and same problem.

Another Windows 7 computer running Firefox 56 does not have this symptom so my next step was installing Firefox 56 which worked. I installed each version incrementally until I found where this started - version 64 works fine, version 65 refreshes when I press "t".

I am so confused.

HELP!!! The thousands of pdf files on my computer and two external hard drives are now Firefox html files. I did NOT do anything do cause this problem. Also, when I try to save MS Word files as pdf files, they are saved as Firefox html files. Yes, I've double-checked the options setting and it says pdf files. HOW CAN I FIX THIS???

I have just switched to a new Macbook laptop. If firefox, when clicking on the bookmark star in the address field, the drop down box opens to edit the bookmark. When clicking on Choose Bookmark, the list that opens contains only 6 lines of folders to choose from. With my last few computers, I was easily able to search and get an answer on how to increase the number of lines from 6 to whatever I wanted. Unfortunately, I never wrote it down and now I cannot recall how to do this. Can anyone tell me how to do this? Thank you!

Hello,

I recently had to switch back to my laptop and noticed that firefox is micro-stuttering (missing a couple of frame at worse) at a somewhat regular interval. Which is very noticable and head-ache inducing when watching a youtube video.

I tried to disable every plugins that I have, switching to a new profile, setting browser.sessionstore.max_tabs_undo and browser.sessionstore.max_windows_undo to 0, closing everything in the background, clearing cookies caches and etc.

Nothing worked, I noticed that disabling window's "Hardware-Accelerated GPU Scheduling" helped. With it on I've got a very regular micro stutter (every 10 seconds) whereas with it turned off I "only" get a microstutter once every 20/30 ish seconds. Therefore I suspect some shenanigans with optimus drivers but I don't know for sure how to confirm. I tried to force firefox to use the integrated gpu with nvidia pannel but it didn't help.

I would have capture a video to show off the problem but everytime I start recording (with lenovo's nerve sense capture software) the problem totally disappears !

Anyone have any ideas about what could be happening / how to diagnose more precisely the problem ? Thanks for reading.

specs :Windows 10 (x64), Firefox 78.0.1 (x64), Intel Core i5-7300HQ, optimus GPUS : Intel HD Graphics 630 + NVIDIA GeForce GTX 1060 (Max-Q)

This is very frustrating and I hope you can help me. Every time Firefox updates the tabs move up to the top of the browser, when I need them below the bookmarks bar, where they used to be. I did get instructions on how to do it for v. 72 (I think), but now I've updated to v. 78 and the tabs are again at the top. The instructions for changing the css: file go up to v. 74 only. Also, in the css: file I'm not sure how much of what's already there should be replace. The entire file? Or? This is probably frustrating for a whole raft of people, but for older ones like me (I'm 76) it's particularly maddening. I would appreciate any help I can get. Also, where would I submit my suggestion to Mozilla to just add a blasted toggle for moving the tabs back and forth. It would make a whole lot of people happy. BTW, I'm attaching a screenshot of the first page of what appears to be at least 8 pages of css: code. Should I delete all of it or...? Thanks for any help the community can give.

I have a Dell Lattitude E5570 running Windows 64 Professional. I use Firefox to connect to the web. Recently I had fibre broadband fitted to the house by BT and with it a BT Smart Hub 2.

On initial setup everything was fine, my QNAP NAS was picked up and I could access it and I could access the BT Hub. However, after only a couple of days I can no longer access the BT Hub using the IP address or my NAS. Firefox simply says 'Unable to connect to server' whenever I put in the IP address. For the NAS I get a message saying 'cannot connect to device, check that the device and your computer are on the same subnet'.

My iPhone however, which is also connected to the internet via my BT hub can access both my NAS and BT Smart Hub 2 .

Strange thing is Firefox would never connect to my Asus router before either. I've even tried connecting my computer directly to both the BT router and the NAS with an ethernet cable but still no joy.

I have checked my windows firewall and Firefox is on there as an allowed app. I have no trouble connecting to any other website via Firefox just my BT router and my NAS. I have removed Firefox and re-installed it as advised but still no joy.

When accessing the NAS via my iPhone on the BT app it says the NAS is connected to my wi-fi as are my Hive, Sonos, Amazon Firestick and laptop.

I have no idea what the 'subnet' message means not knowing what that is or where to look to see if this is the issue. Oh, and I have tried accessing the BT Hub and the NAS using Chrome, Microsoft Edge and Internet Explorer but to no avail.

Any help would be appreciated.

Thanks

Paul.

I can access my router setup page which is "192.168.0.1" or "tplinklogin.net" via other browsers without any problem. But with Firefox I can't access them anyway! But my internet is working fine and other websites are working fine too in firefox. Follow the screenshot please!!

Any kind of help would be appreciated! Thanks in advance!!

With recent updates shave had 3 problems on my desktop (Windows 7). All settings are default .... everything was fine until the last 2 or 3 updates.... have changed 0 settings over this time. AV is Kaspersky but I have it turned off. FF 78.0.1

1. Every Video I try and watch now has sound off by default ... PITA unmuting all the time. That's what Id like if it is a pop-up I have no interest in but if I PLAY the video, I want to hear it. This has been going on since maybe 4 updates back.

2. It has become a thing of late for authors not to bother writing, but to just include a bunch of twitter posts. I'm not so perturbed about not being able to see them (tho would like to know whats blocking them) ... just a gray box that jumps around, but after scrolling past them the page / text is jumping around. This started 2 updates back

3. With the last update, a new one .... for a game I play with my kids on line, we use a map

https://ballisticmystix.net/?p=map

The page pulls in a grid map which I can no longer see, map area is all black. I just see the names and a grid pattern. Weird thing is It works fine on my laptop. This started on desktop just a few days ago

4. For whatever reason, my laptop "lost" most of its bookmarks

Note: I am typing from my laptop ... all but item 4 are issues on the desktop

Firefox version: 78.0.1

Firefox recently changed the behaviour when clicking on downloaded PDFs in the Firefox Downloads panel. While all other downloaded files are opened with the system default program when clicking on them, PDFs are opened with the built-in Firefox viewer.

This is counter intuitive. If Firefox is the system default PDF viewer, this separate treatment of PDFs is not necessary (the system default redirects back to Firefox). If Firefox is not the system default PDF viewer, users need to take extra steps to open a PDF in the system viewer (open the folder, click on the file; also documented [https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-ano...]). Therefore, this change creates no benefit for those who use Firefox as the system default PDF viewer, while reducing usability for those who use a different system PDF viewer (e.g., Acrobat).

Example use case:

• Browse to a PDF URL: use the Firefox built-in viewer, because it is fast and convenient. A more sophisticated viewer is not necessary because the document is only viewed, not edited.
• Download a PDF: use the system default viewer (e.g., Acrobat), for example for annotation.

It seems clear that this change has reduced usability for no functional improvement, while the common combined use case of Firefox for PDF URLs and professional readers (e.g., Acrobat) for downloaded PDFs has become more difficult.

Hello,

i have a problem with a personal webextensions, that i have written for my personal use. I add a new protocol in windows 10 pe registry (player://) and use this to start a special windows script.

My extensions put an new menu-entry on right click and rewrite the url from the tab with the the protocol (play://https://www.youtube.com/asanexample).

Now he does nothing in the newest versions of Firefox. I use

browser.tabs.update({url: "play://https://www.youtube.com/asanexample"});

and nothing happends. The tab.url says www.youtube.com, but nothing happends. But when i call

function updateFirstTab(tabs) { var updating = browser.tabs.update(tabs.id, { // active: true, // loadReplace: true, url: "play://https://www.youtube.com/asanexample"}); updating.then(onUpdated, onError); }

var querying = browser.tabs.query({currentWindow:true}); querying.then(updateFirstTab, onError);

and then an:

browser.tabs.create({

   		url:"https://example.org"
 		});

He loads the protocol page and the new created example.org page.

When i use tabs.create he call the protocol, like my old tabs.update code.

Is that an security change? But why tabs.update functioned when i call a tabs.create after it? When i must use tabs.create how can i seamlessly close the newly created tab after call the protocol?

I hope it is a bug in web extension;), why my code has functioned with the tabs.update() so many firefox version along.

thx

Hi, When I turned on my computer this morning, my bookmarks were not there. I've tried the steps laid out by Firefox, but no success. I tried another browser, Safari, which I seldom use, and Safari bookmarks were still there. I have many different bookmarks in Firefox so I'd rather not switch over to Safari unless absolutely necessary. Nothing else is missing, so I doubt if I've been hacked. I did check a bank account, which was fine. I'm not a high profile person, so I doubt if I've been targeted. And I see the pic of the lock closed in the URL bar constantly. Any thoughts on this would be appreciated. I'm on Mac OS 10.15.5 (Catalina) Firefox 78.0.1 (64bit) Thanks, JJ

HI, How can I change the color of the Font in the Tabs? You know when you have 2-3 tabs open and you look at the names of the website. How can I change the color from white to black? I have the latest Mozilla Firefox. and Windows 10. Sheri

The "Flexible Space" item is useful to separate icons on my Firefox (78.0.1, 64-bit, Windows 10) toolbar, but I don't need it as wide as the default. Is it possible to modify the size, and how would I go about it?

The latest update placed Close Tabs to the Right and Close Other Tabs in a submenu. To me this is a confusing change as I now need more clicks to achieve the same thing.

Also I feel that the context menus are too crowded in Firefox. I suggest a padding between the items.

I have been looking into hosting my own firefox send server. Does anyone know ways I can secure the server so that malicious files or other inappropriate content is not hosted on my server?

I always keep firefox updated, as recommended. Have privacy and ad-blocking extensions installed, as recommended. After ff update ALL extensions are disabled, without an option to enable them. No warning at all! WTF firefox team!

At least make an warning "this update will f**k all Your privacy, ad-blocking, anti phishing, password ... etc extensions

I prefer extensions to "protection report dashboard, better pdf experience", for REAL ?!?!
