Some websites like youtube, twitter, reddit and maybe many more don't properly load. On youtube videos freeze after a couple of minutes, I don't have any of these other issues on other browsers like Chrome

After removing other elements, I'm left with a map, which I was able to expand to the top and sides, but not the bottom area.

The site is https://earthexplorer.usgs.gov/.

Hello, FireFox Updated my 17" MacBook Pro- High Sierra on July 30, 2023 successfully to 115.03. There was another update today Aug 1st 115.1esr, which said it Failed for an unknown reason. Can anyone tell me how I can find out what happened? See attached update message.

Thanks in advance for your help.

Hello team,

After the most recent update I have been having issues with the Youtube video playback. Upon loading a video it works fine, however once I click on the progress bar to skip to a certain point of the video, the video pauses, the progress bar tracker gets set to 0:00, the video starts buffering and I have to click 3-4 additional times on the specific time I want to skip forward to, in order for the video to even continue playing. I have restarted my PC, cleared cache and cookies, re-installed the browser and nothing works. Mind you, when trying to watch videos on either Edge or Chrome, there is no such issue and the progress bar works fine. I really do enjoy Mozilla, but if this keeps up I will have to change browsers it is bugging the hell out of me.

Looking forward to receiving any help.

Kind regards, Petar

Hello there, I'm getting following warnings when I set report-to directive.

Content-Security-Policy: Couldn’t process unknown directive ‘report-to’ Content-Security-Policy: This site (http://puvipavan.local) has a Report-Only policy without a report URI. CSP will not block and cannot report violations of this policy.

These are the passed headers:

Am I missing something? I'm using the latest version of Firefox as of July-31-2023(115.0.3 (64-bit))

firefox monitor does not allow me to sign in using dashlane password manager. Every other website responds by either filling in the name and password, or asking if I want to use Dashlane data. Please help. thanks

Just to preface I have already tried looking for a similar issue in support and most of the answers are like "just make sure to not be in private browsing" but I am sure that I am not and my extensions are all allowed in private browsing anyways. I also know this is not a theme issue as after I removed ublock origin and re-added it to firefox the extension icon showed up in the menu just like usual, but I do not want to do this for every single extension as I have a large amount and I am worried about personal settings that I have saved being undone. In the past I have used this same firefox setup without any of these issues whatsoever and without changing any settings since then.

The main issue is that when I click the extensions menu toolbar icon (the puzzle piece) it only takes me to about:addons. On this page I can confirm all my extensions are there, and I know that they are working, due to things like ads still being blocked from ublock origin or tracking links being blocked from clearURLs. However there is no icon for them after clicking/right clicking the the extensions puzzle piece, or when using the "customize toolbar" feature, or in the overflow menu, or in any other possible place. I have also tried telling the toolbar to reset to default and this does not help. Since the puzzle piece icon never shows me a menu, there is no way to right-click an extension and get the menu option to "pin to toolbar" as this option can't be found in the about:addons page as far as I have found.

Is there any way to fix this beyond just re-adding every single one of my extensions?

I'm a web developer working on an app running in Docker on my MacBook. Chrome, Edge and Safari trust the self-signed certificate that has been imported into the Mac's root certificate store and have no security issues, but when I try and access the web app, I'm hit with "Warning: Potential Security Risk Ahead" and the error code is MOZILLA_PKIX_ERROR_CA_CERT_USED_AS_END_ENTITY

I really miss Firefox, particularly the multi-account containers feature. What do I need to do so that Firefox will trust my certificate for my local web app?

I want to disable overscroll. For those who don't know: it's the bouncy animation when you use scroll using a two-finger gesture past the beginning or end of a scrollable region.

The bouncing is an animation, and with animations disabled on my system, having this animation is an accessibility issue.

I guess I could split this question in two:

1. Can Mozilla please change Firefox so that it doesn't do this animation when animations are supposed to be disabled? 2. How can I disable this overscroll behaviour manually, separately from other animations?

Hi all,

I’m trying to make aware people of the recent Google movements to close gate the internet to their services and I suggest to folks to move to Firefox.

One of my colleagues encounters a problem clearly visible on the image attached (it shows correctly on my mac).

It's not as bad on my mac, where I only have issues every now and then - I received an email this morning on my work email, and all the apostrophes were replaced with Registered symbol (R in a circle).

I noticed that not allowing websites to use their own fonts fixes the issue (unticking "Allow pages to choose their own fonts, instead of your selections above") but I would like to be able to view sites the way the developers intented rather than forcing my browsers default fonts.

Any ideas?

Many thanks

I have four active Firefox windows, each with quite a few tabs. I have been closing and re-opening Firefox with no issue until today. Earlier this week I updated my Mac OS to Ventura 13.5, and Firefox was still operating normally after the installation (closing and re-opening with all windows and tabs intact).

Today however, when I restarted Firefox, no windows opened automatically. I closed and restarted a few times, and finally one window opened intact; however the other three windows (still dispalyed on the "Windows" menu) refuse to open. When I look at my Firefox app on my iPhone, it also shows all the tabs intact.

What can I do to get these to open? I am running Firefox version 115.0.3.

The spell checker isn't working for me. I've found old answers to this:

"You can see which dictionary is selected if you right-click in a text area and open the Languages sub menu. At least one dictionary should be installed and have a check mark to indicate that it is selected.

   open the "Add Dictionaries" link to install a dictionary if you do not have one. 

The spelling checker is enabled if [X] "Check Spelling" in the right-click context menu has a checkmark.

You can enable or disable spell checking globally:

   Options/Preferences -> General: Language and Appearance: "Check your spelling as you type" 

You can look here for dictionaries:

   https://addons.mozilla.org/firefox/language-tools/ 

Note that for spell check you need a dictionary. A language pack provides string translations for the user interface.

   https://support.mozilla.org/en-US/kb/use-firefox-interface-other-languages-language-pack 

You can check the layout.spellcheckDefault pref on the about:config page.

   http://kb.mozillazine.org/layout.spellcheckDefault "'

But I don't understand what most of this means!

I don't find 'language' because I don't know where to find a "text box containing more than one line" I'd have thought this was one, but the option does not come up here when I right click.

I realise this is probably me being dense, but can someone help in simple terms, please? Thanks.

My windows install in my dualboot pc is unable to open at the moment, I can access the windows files from my linux. But i need the firefox data on that pc that I kept. I don't remember which email I used on that account so I'm kind of stuck on getting my data from online. Is there a way to recieve all the data from another drive without opening firefox?

Websites displayed in Firefox use ridiculously low contrast for their text. This composition box is a prime example. 30 years ago when my eyes were 30 years younger web sites tended to use BLACK TEXT on WHITE BACKGROUNDS, with fairly THICK FONTS.

Over the last 5 to 10 years websites and/or browsers have adopted much the terrible Apple Style used in its packaging: Light Gray Text on Lighter Gray Backgrounds *and* very Thin Fonts. Fortunately websites/browsers have not yet generally followed Apple's lead to the use of about 4 point fonts.

    I'm using:
         * Firefox Browser 115.0.3
         * MacBook Pro 15"
         * macOS Monterey  ver. 12.6.7

How can I greatly increase the contrast and the density of text displayed by the Firefox Browser?

Recently, my FireFox has been acting a bit strange when it comes to playing videos. I am using a site called Udemy to watch a video course I'm taking, however, the videos don't seem to play for either a long time, or until I tab into YouTube and play a video there.

This issue is not only with Udemy however, as the YouTube videos also take longer than normal to start playing; It's not only at the start of the video either (whilst waiting for the video to fully load), It's all the time, between every pause I have to wait around 3-4 seconds before It actually start playing.

The issue is clearly something to do with videos but I find it very strange that playing a YouTube video forces my Udemy video to load.

It's been a real struggle trying to get todays course day done, since every time I pause the video I end up having to wait a while or go to YouTube and play a video to make it continue.

I've gone through all the basic troubleshooting recommended for video issues on here and other places: Turn of hardware encoding, lower security levels, enabling autoplay etc etc; absolutely no luck. I've tried disabling extensions one by one, disabling themes, running FireFox in troubleshoot mode, clearing all data/history/cookies/cache, making sure DRM-controlled content is enabled as well as trying it disabled. You name it, I feel like I've tried it at this point... Any suggestions are highly appreciated!

Another thing to add is Chrome isn't having this issue, neither is Safari.

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

I've tried all the ways mentioned to delete my search history, other than deleting each entry individually. Three particular websites just won't go. Is there some umbrella action that will delete all these references?
