Firefox Support Forum

When I start to type a reply to a Facebook post, the page scrolls down so that the line I am typing disappears one line below the bottom of the screen. I have to scroll down to see what I'm typing. Also, it jumps down the same way whenever I hit the backspace key to edit what I'm typing.

I discovered a previous (archived) post on this forum that suggested using "about.config" and making sure that the value setting for browser.backspace_action is equal to 2. But that didn't change the annoying behavior. Is there any other value I should try? It's not clear what the number means.

Nor did setting browser.backspace to true (or to false) seem to help with the unwanted jumping upon use of the backspace key.

This only seems to happen with Facebook, but it's quite annoying.

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

When I click on a "mailto" link, Firefox (my default browser) opens a new tab, then immediately close that tab without waiting for my to interact with it. No draft email is created. I see that other users have reported this behavior in the past, and I've tried the suggested remedies without success. Specifically, I ran Malwarebytes, and it found no threats. I then started Firefox (on the Mac) via the Option key (to start it without ad-ons), and that does not change the behavior. I'm on ver 99.0.1 of FF, which is up to date as of 4/20/2022 (today). My Mac OS is also up to date (ver 12.3.1). My Mac is a 2021 MacBookPro with the Apple M1 Pro chip. I use gmail. OTHER BROWSER (like Safari and Chrome) can open "mailto" links in a new tab in FF (which is my default browser, and used for mailto links) just fine! Here is an example of the URL that I see in a new FF tab opened via Chome: https://mail.google.com/mail/u/0/?fs=1&tf=cm&source=mailto&su=Cover+of+the+River+Journal&to=Steve+Mones%3Cstevenmones@optonline.net%3E Any help would be appreciated. - Thanks, Jim

I have successfully logged into my Docusign account from the Firefox web browser on my Windows 10 computer up until now. All of a sudden when I try to log in, Docusign tells me I've entered an invalid password. The password is valid, I've tried it on Microsoft Edge and in the Apple iOS Docusign app and have successfully logged in. They both prompt me to get a code from the Microsoft Authenticator and I do not get that prompt when I attempt to log in thru Firefox web browser.

I work on kubuntu 20.04 with plasma 5.18.8 desktop environment. I have a QtCurve-based custom application style, which I almost match with css for GTK apps. Firefox has to be an exception by itself! Not only that, but it changes my ability to customize its interface, from time to time and even changes access to such ability, on some updates.

My scrollbar customizations in userChrome.css and userContent.css do not work any more (other CSS changes still work, for menu/addressbar/tabbar/bookmarksbar orderint and tab styling). I had to resort to settings in user.js file, to get a 20px width scrollbar, suitable for my big screen, but... it gets very wide when I increase the focus, on some webpages and becomes very ugly! Furthermore, I cannot make sense of the proper use of "ui.themedScrollbar*" settings and the scrollbar and its slider result in the same color. These are my settings in user.js:

user_pref("widget.content.gtk-theme-override", "backwater"); user_pref("widget.non-native-theme.enabled", false); // Use GTK-3.0 gtk.css: set to false user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true); // Use userChrome.css & userContent.css: set to true user_pref("widget.gtk.alt-theme.scrollbar_active", true); user_pref("widget.non-native-theme.scrollbar.size.override", 20); // If nothing else works, fix scrollbar width to 20px user_pref("widget.non-native-theme.gtk.scrollbar.round-thumb", false); user_pref("widget.non-native-theme.gtk.scrollbar.thumb-size", 1.0); // originally 0.75 user_pref("widget.non-native-theme.gtk.scrollbar.allow-buttons", true); // it was true, anyway... user_pref("layout.css.cached-scrollbar-styles.enabled", false); user_pref("layout.css.color-mix.enabled", true); user_pref("widget.non-native-theme.scrollbar.style", 4); // wide scrollbar theme: set to 4 user_pref("ui.themedScrollbar", "#bad1f5"); user_pref("ui.themedScrollbarInactive", "#668cc4"); user_pref("ui.themedScrollbarThumb", "#e4e4e4"); user_pref("ui.themedScrollbarThumbHover", "#e4e4e4"); user_pref("ui.themedScrollbarThumbActive", "#668cc4"); user_pref("ui.themedScrollbarThumbInactive", "#bad1f5"); user_pref("browser.dom.window.dump.enabled", false); user_pref("extensions.ui.sitepermission.hidden", false); user_pref("fission.experiment.max-origins.qualified", true);

Either with the "ui.themedScrollbar*" settings or without them (and cleared from the prefs.js file), the scrollbar and its slider result in the same color, unless I (tryingly) click on some place on the scrollbar outside its slider; then I can see the slider, _only_ for the duration of the mouse-down event (which causes up or down page-hight scrolling).

The default, very thin scrollbar, as well as my modified wide scrollbar with invisible slider are both useless to me! I have even tried fx-autoconfig (https://github.com/MrOtherGuy/fx-autoconfig) to make the scrollbar CSS work, but no result. At this point, I am considering switching to another browser, despite the trust I have to mozilla, for my data and privacy.

This sounds like it's a Meetup problem, and in fact it may be, but now I am having doubts.

The problem is that I can't upload photos to a Meetup event. (This will mostly just be a problem for Meetup organizers.) When I click on "Save photo", nothing happens. No error message, nothing. It's as if the "Save Photo" button has been disabled. Firefox is my browser while I access Meetup.com, and I have the latest and greatest version of Firefox.

I contacted Meetup and they haven't been able to solve the problem; they suggested that I clear my cache and my cookies and try again, but I get the same result. HOWEVER, when I go into Microsoft Edge, I can upload photos with no problem. So I have a work-around: use Microsoft Edge to upload photos. So my question to you centers around: why does this work perfectly in Microsoft Edge, but it doesn't in the latest version of Firefox?

To test the possibility that it's a bug on my personal desktop computer, I went to the public library and tried the same experiment, with the same result. So I don't think it's problem with my personal desktop computer.

One other piece of information: the exact same thing happens (failure to update photo, that is) when I have the photo open in another application (Photoshop), even if I try to "save photo" to Meetup in Microsoft Edge. Then when I close the other application (Photoshop in this case), Microsoft Edge lets me "save photo."

I know that Firefox really doesn't want me to try to revert to a previous version, and it makes me nervous too, but I am suspecting that something in the latest Firefox version actually introduced a problem. (Or maybe triggered a Meetup bug of some sort; I still haven't located the problem.) I've been on Meetup.com for years, I've had Firefox for years, they've worked together to upload photos in the past for years.

If you want to get into the details, below, for what it is worth, is my initial question to the Meetup support people (with whom I am still in a conversation).

I can't upload a photo for my event. In fact, I cannot upload a photo for any event at all. I deleted a couple of photos and an album because maybe our group had too many, but that didn't work. I can't even upload a photo that I had previously uploaded to a different event, so I don't think that the problem is with the photo itself.

Here's what happens. 1. Edit the draft of my meetup. 2. Click on "upload photo." The photo is 1827 x 1009 pixels, total size 63 KB. 3. I click on "Upload photo", then in "add photo" I click on "upload photo" again. I browse for the photo and select it. 4. The "crop your photo" screen appears, with the selected photo in it. It's already the size I want, so I click on "Save Photo".(Cropping doesn't help either.) 5. Nothing happens. No error message, nothing. The only think I can click on is "cancel," which takes me out to the previous screen. - - - - - -

Hello. Since I use the bookmark bar and fullscreen mode a lot, I would like to be able to see the bookmark bar in fullscreen, not on every tab, but only in a new (empty) tab, so that I can avoid disabling fullscreen to access the bookmark bar and at the same time not having any part of the interface visible unless I'm in a new tab. Thanks in advance for any reply!

Ever since the "What's new with Firefox" page contained an ad for a movie, I want to disable it as I find it objectionable that a decision to include advertising on that page was made. How does one disable this page from being displayed after Firefox is updated and restarted?

Hi! Since yesterday, in Outlook, my font size became very tiny for subjects and categories. I can barely see it. Can you please restore them to normal sizes?? I am desperate trying to read them. Thank you! Shirley Savva

I have a user who runs SRS/Crystal Reports on their Windows 11 Lenovo laptop, but every time we go to the website where a Java-enabled pop-up window for viewing spreadsheets is supposed to load we keep getting a "A plugin is required to play this content" error message, but no option to install/approve the running of Javascript.

I have downloaded and installed the JRE and JDK on the endpoint device, but still no luck getting Firefox to load it. I am running the 32-bit version of the web browser, not 64-bit, so I am kind of stumped about how to proceed from here.

Is there a place I can manually download/install these Java plug-ins?

Thanks.

I have tried this several times over a few years, and have never got it to work I know it must be something I am doing wrong because if it was a glitch or bug, it would have been fixed by now. Usually I need to do this if I need to reinstall the OS, (Windows and Linux), or a new pc, the usual, but this time I had a major crash, so I'm starting over.

Anyway I have signed in on my pc to my FF account, and went through the menu to turn on sync, and I get to the page where is says, "when ready click next to display the QR code". I get my android out, open FF, sign in, click the "Scan" button, the FF scanner opens,, I open the QR code on the pc, (I have also went to the website to get a QR code). Then either way I scan the code, and get an errror msg "Must scan from inside FF". I am scanning from inside FF, with the FF QR scanner.

I don't uinderstand how of the 20 or more times I have tried to do this, I can't get it to work. I don't understand how I screw up every times, over a few years. But I also know as I said, if it was a bug MOzilla would have fixed it by now. Usually I give up on that and just log into both the pc and the phone, close both browsers and reopen them and it will go ahead and sync.

But not this time, I am unable to get it to sync for anything. I've been working on this for 3 days now, and at this point I'm confused, I don't remember what I have and have not done. Let me add, and I don't know if this will make a difference, I don't think so, but what do I know? Originally this all started, when I had to reset my password. I tried for 4 days there to get a recovery code to work. (The following is just to describe what I've done, and is not a second question) I had one downloaded, and saved on my pc. But no matter what route I took to go through the reset process, exactly as described in the help file, I never could get a place to enter the code. I read every article I could about it, and finally it seemed easier to just reset the password and resync than try to get the code to work.

Which is why I am sitting here, desperatly needing to sync my data, but unable to. If anyone can tell me what I need to do I will appreciate it. If you need any more information, just let me know.

I opened Firefox as usually, but passwords are missing, only logins are available. There is also a file called logins.json-1.corrupt in the profile folder.

Renaming it back to logins.json with restarting the computer does not work.

There are no previous versions of these two files available in the system.

Please let me know how I can recover passwords, may be with a special software.

Thank you!

I use Last Pass for passwords & it's worked in the past on Firefox. After updating Firefox, the Last Pass extension in by toolbar is black - in the past I would click that, open the Last Pass page to sign in, then the icon turns red and functions. Now when I click the icon a frozen page comes up that never loads. I can sign in to the Last Pass webpage, but that doesn't turn on the extension.

Any advice appreciated - thanks!

I'm not sure what happened, but the picture-in-picture extension isn't working anymore and there's a sort of "script" (see uploaded image) that shows up over the top of videos, including but not limited to the ones on YouTube. I used to be able to still use the extension by using keyboard commands at first (ctrl shift ]), but now that doesn't work either.

Like the title says, whenever I try to zoom out of an image to make it smaller, it causes the image to zoom out very far in just one scroll "tick".

To be more specific, I'm talking about just scrolling (not using ctrl+scroll). An example would be with Piskel.com where you simply use the scroll wheel to zoom the canvas.

Zooming in is perfectly fine, but when I try to zoom out it seems to zoom out by 3 or 4 ticks. On some websites, such as Piskel, it even it zooms the image out all the way making it very small and impossible to see (It does it with just one scroll tick).

My question is if there is a way to change or fix the zooming, making things zoom out more incrementally. (I recently switched from Chrome which didn't have this problem)

I've just started noticing in Firefox 99 on Arch Linux that Firefox is using the wrong font when the font-family is given as "ui-monospace/other fonts..., monospace". This looks similar to the issue mentioned here: https://support.mozilla.org/en-US/questions/1351497

The inspector for these websites underlines "monospace" as the active font, but then uses a non-monospace font (in my case, Bitstream Vera Sans) to display the content. This does not happen when the font-family is "monospace,monospace" or "monospace". I can't quite figure out exactly what causes the font to be chosen incorrectly: sometimes it does show up if I have the preceding fonts installed, e.g. Consolas or Liberation Mono, but other instances do not look as intended.

Currently, I have fontconfig set up such that: $ fc-match :family=ui-monospace VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman" $ fc-match :family=monospace VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman"

Firefox's fonts in about:preferences are configured as all defaults: Serif: Bitstream Vera Serif Sans: Bitstream Vera Sans Monospace: Bitstream Vera Sans Mono

Hi Mozilla Firefox team,
