Firefox Support Forum

Is there any way (as in Thunderbird, via layouts.css.devPixelsperPx) to enlarge everything on a given monitor/display/colorDepth setting? Or an approach using userChrome.css that impacts everything, not just displayed text in the browser. Yes, this is a "tired old eyes" (excessive nanoseconds spent looking at bigger and bigger displays with higher and higher resolution) type question. My setup is multiple boot OS including Windows 11, Ubuntu, Manjaro, Arch. In each Firefox is the default browser, but Chrome and Edge seem to have more fine-grained controls for managing the chrome display than Mozilla. Using the latest 64-bit Firefox (100.02) if that's helpful.

Firefox always uses excessive GPU memory when I watch video and livestream. about:memory shows that the explict GPU memory allocation is only about 200 MB but in the task manager the GPU memory usage is 1GB, and the latter doesn't decrease even if I close the tab. I suspect that this is a memory leak. I searched for Bugzilla and found a similar issue that has been existing for years: https://bugzilla.mozilla.org/show_bug.cgi?id=1386177

I have tried the suggestions as described in the following article: https://support.mozilla.org/bm/questions/1273784 However, am still having the issue. It's as if the settings are totally ignored. I am using version 108.0a1 of Firefox developer edition. Ideally what am trying to achieve is away to disable all features of ETP. I figured setting it to custom with all values unchecked would have done the trick but it's not working. What works is if I add the site to the list of Exceptions for Enhanced Tracking Protection, then I will see all Ads loaded just fine on the page. However, this is not viable for me as I have a large list of sites that I visit, and I need to see the ads on them.

Does anyone know of a way to get around this feature in FF?

Is there another setting am missing from the previous article?

Hello,

Please add this feature in Firefox and Firefox developer edition

I am wondering when i open firefox developer edition. All the tabs will be open during stating firefox developer edition.For better understanding this feature is already in google chrome.Please search this in google

Open a specific page or set of pages

Prior to the last update, Firefox was auto resizing my tab background area (I don't know the technical name of this, but its the menu area behind the tabs) to fit more tabs as I opened them, up to a certain number of open tabs. Now the tab background area remains at its full size from the start even if I have only 1 tab open. I prefer the old behavior and I'm not sure what userchrome setting I need to adjust in order to get back to it. The line that is causing the issue is as follows

1. main-window {

 /*--tab-min-height: unset !important; */
 --tab-min-height: 38px;
 --tabs-lines: 8;     /* THIS LINE CAUSES THE PROBLEM */
 --tab_min_width_mlt: 186px;
 --tab_max_width_mlt: 186px;
 --tab-min-height_mlt: 38px;

}

I can reduce it to a lower number but when I do that I am stuck with the tab scrolling behavior that I don't want. Perhaps there is a setting to auto resize the tab area that I'm unaware of. I would appreciate any assistance. Thanks.

I need to reset my password and I have all my firefox files from "appdata/roaming//monzilla/firefox" but will I be able to restore all my data from it after the reset or will the reset prevent anything? Will it work?

I want to be able to sync my data and know my password for this account.

I am aware that there is a guide for restoring profile data, but I dont know what happens after I reset the password and still try to restore the profile.

The first image is with Fx 103 https://i.imgur.com/r9L3MtM.jpg

This next one is with Fx 102 https://i.imgur.com/N8p1gis.jpg

Others having resolutions other than 1920 x 1080 are having the same problem. Any help would be appreciated

I look for the smallest zoom possible on the Firefox settings to suit my eyes and I don't find it, there's 67% and 80%. 67 is too small and 80 too big. Unlike other browsers who offer 75% of zoom level, I really want it on Firefox too! If this could come up, it'll look pleasing!

Hi guys. I'm on a Lenovo laptop, using Windows 11. Was NOT experiencing this issue (or any other issues) till today. That is, I've been able to download PDFs attached to Yahoo email for years, including recently (till today).

Trying to get Firefox to be DEFAULT instead of MS Edge, I changed some 'Apps associated with File Types', selecting Firefox as default for all file types that seemed appropriate, BUT, this issue then began.

Feeling I went too far, and should go step at a time, I reset All File Type settings back to default (MS recommended settings). Still can't open attached PDFs. I tried an Excel attachment and it opened fine.

Error I get is: "Firefox Can’t Open This Page To protect your security, dl-mail.ymail.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window."

The emails I used to recreate the error, were sending an email to myself, and attaching a PDF.

Other things I tried: I used Firefox with gmail email and the PDF attachment downloaded fine. I used MS Edge with Yahoo email and PDF attachment downloaded fine. Also, btw, CAN view a PDF attachment with Yahoo email. Just now download.

I CAN "open it in a new window" as the error suggests, than print to PDF, but don't want to live the rest of my life doing that.

Thanks in advance for any help that can be offered!!

Certain fonts are displayed not as what I set them to in Firefox's settings.

At first, I thought it was a windows OS font related issue- it's not.

I've followed everything here: https://support.mozilla.org/en-US/questions/1323130 (The answer support link is inaccessible. But following the answer did not fix my issue.)

Also looked to see if any of my add-ons are affecting it. I've disabled them on the sites (in the screenshot) but the fonts are still displayed as attached. Checked to see if the add-on uBLOCK is disabling remote fonts, that feature is not checked so that's not the issue.

Please help, thank you.

I cannot say if the last update was the change. I did not have the issue of bookmarked sites and when I log in, no user name or password is provided, as what happens now. Those bookmarks' login information IS still in my Firefox's about:logins, but now they are not being automatically presented. Even after finding the login credentials, logging in & out, returning to sign-in, the credentials just used are not recalled for use again.

That was not always the case and I would like to know if there's a 'setting' now that needs to be 'toggled' so 'Manage Logins' will work as it was did.

98.0.2 (64-bit)

Access to Google sites (Gmail, Google Search, Google Calendar) with Firefox (v. 100.0, 64-bit) is very irregular. I can sometimes open the pages, but can't, e.g., edit calendar entries. Often when I click a bookmark (in the Bookmarks Bar), or enter the URL for a Google site, nothing happens. Clicking other bookmarks opens the corresponding pages. Only Google sites seem to be affected. Is FF blocking Google?

firefox not opening since 2022-01 Cumulative Update for Windows 11 for x64-based Systems (KB5008353). I reloaded Firefox. Google Chrome and Microsoft edge work OK. Task manager shows running but stats never change 0% CPU/0.2MB Memory

i somehow can't find the 'mozilla' folder in 'appdata/roaming'. i was trying to open my profile folder but it displays the message saying that it's 'unavailable'. i digged in further into the problem and found out that i had no such mozilla folder in appdata. is there any way to fix this problem? or am i just missing something?

I have turned on Hide pointer while typing in Mouse Properties, see pic. It works in Notepad, but not in Firefox.

Mouse Properties can be accessed from Windows Settings > Bluetooth & devices > Mouse. Here click on Additional mouse settings.

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

Hey guys,

is it possible to disable the "saved logins" dropdown, whenever a password/email field gets focus? (see image)

I've already disabled "Autofill logins and passwords", but that just disables not directly autofilling the field.

I want to disable this field, since I can still use saved logins via right click "use saved password", which i prefer.

Its no form field, i've already checked that + it occurs on all login pages.

The only options i've found where: "signon.showAutoCompleteOrigins" - hides from which website and "signon.showAutoCompleteFooter", which hides the lower part with "view saved logins"

Is there a way to disable this Dropdown completly, without loosing the auto save/ask to save new passwords?

Kind Regards

Firefox 104.0.1 (64-bit) - Fresh install (just imported logins)

Firefox browser opens minimized - about half size. Support article suggests a refresh, tried that and it works for the first time the browser is opened after the refresh and then reverts to the same size.

Another suggestion was to delete the xulstore.json file as it may be corrupt. Done that several times. Each time, that solution works for the first time the browser is opened. Beginning with the second time, the behavior returns.

I have also tried uninstalling and reinstalling Firefox. Same result. Works for the first time the browser is opened.

I have no extensions or plug-ins installed other then what exists from the default browser. I am running the current version of Firefox, Windows 11, fully updated system with plenty of RAM and disk space.

Thanks!

Hi,

Is there a way to remove the "delete" option when right clicking on items in the download history? It's unfortunately right above 'remove from history' and easy to mis-click. It has no confirmation and permanently deletes the file(s) without sending to the recycle bin which is quite annoying - especially as I'm not sure why you'd want to use this menu to delete something you just downloaded.

Thanks
