Firefox supportforum

This morning I could not log into the Schwab customer website using current Firefox version 123.0 on Windows 11. Reverting to version 122.0b9 solved the problem. Before the reversion I tried clearing cache, history, passwords, etc, and I tried a full reinstall of version 123.0. What else would prevent a connection to Schwab when other websites worked fine?

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

All of a sudden (started today) Firefox will not load ANY websites, except Mozilla/firefox websites. All previous bookmarks, links, and typed in addresses do not load. No changes to virus protection, browser, or any other updates. Other browsers (chrome, opera) work fine.

I cannot log in to my Gmail account via www.google.pl in the Firefox browser. When I try to log in via www.google.pl, the Bad Request Error 400 message appears. The same problem occurs when I need to confirm login to other websites using a Google account. I simply can't log in anywhere. This problem does not occur in other search engines. A login icon appears on the www.google.com website, but not all related services from Google are available - Google account, Google Play, Gmail, Meet, Chat, Drive, Calendar, and Photos are unavailable - these are just the most important ones that don't work. Cookies are enabled. On December 25, 2023, this problem did not exist. I tried to restore Firefox to an earlier installation date, but it didn't help. I uninstalled the extensions and plug-ins. Unfortunately, the problem remains. Please help me. Regards, Bogaczewicz Bogusława.

I just wrote this blog post and someone suggested I contact you.

I have my default browser set to Firefox on Linux (Debian Bookworm). When I open an http:// or https:// URL, it opens in Firefox, but when I open a file:/// URL, it opens in Chromium. It seems that file:/// URL makes it resort to the MIME type.

Is there anything Firefox can do here or is this a Debian or freedesktop.org issue?

Thanks!

How can I set tabs to automatically preload when I open the browser? I'm just trying to switch from Chrome to Firefox and I can't find such a setting here, although it is a very convenient functionality. I mean that when I open the browser, I can click on any of the tabs and it will be (partially or completely) immediately ready to work without additional loading.

I have to create a new question because when I try to reply to the answers I received the system comes up with an error page.

My version of Firefox is 120.0.1 and has been downloaded from the Mozilla website.

The problems occurs with all PDF file both local and from the internet.

The attachments are highlighted in blue in t he opened PDF file but cannot be opened. There is no way to click on the attachments.

Attached is a screen shot of one PDF file because I cannot attached the PDF file itself

Every time I open a youtube video in fullscreen, firefox crashes. `about:crashes` says "No crash reports have been submitted."

Some information about my system:

• Firefox version: 122.0.1 (64-Bit)
• Macbook Pro M2
• MacOS Sonoma 14.3.1

If there is a way to get more information that you would require (like logs) please describe how I access them, so I can share them.

Firefox is my default browser, but it does not allow me to log in to specific websites. For example, ihg.com, when I click the sign in button nothing happens, I just have a little note at the bottom left "javascript:void(0);" Another example, dutchcrafters.com , when I click Log in with Gmail, nothing happens.

I have tried removing all the content blocking extensions (privacy badgers, ublock origin, etc.), did not fix it. I have tried a firefox refresh, did not fix it. I have tried uninstalling and reinstalling firefox with several device restarts, did not fix it.

I know this must be a firefox specific problem because microsoft edge work perfectly for both of these examples. Any other suggestions to fix this firefox issue?

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

So I've been doing this for years now, as a Youtuber I take an image file from File Explorer (Windows 10) and drag it over to upload the thumbnail to Youtube. But for some reason the last few days I can't drop the file, it just stays there with the mouse when I let go of the button. On a random page it should let me drop the file and show the image but it doesn't, and it also won't drop if I try a google image search.

I have tried this on Edge and Chrome and the problem only seems to exist on Firefox.

[My screenshot button hides the mouse in pictures but it's attached to that blue semi-transparent square, trying to drop a file but can't.]

I have Firefox as my default browser instead of Microsoft Edge on my HP laptop. I've tried everything under the sun to make Google my default search engine over Microsoft Bing, and no matter what it won't stop rerouting me to Bing. I can go to www.google.com and type directly in the search bar and it STILL reroutes me to Bing, even when my settings list Google as my default search engine of the search bar. Can I block Bing as a website altogether? HP support only offered to connect me with a specialized team that costs money. Please help.

Hi there

I have found that certain websites aren't loading properly and that images aren't being displayed whilst the majority of pages are loading properly. Can someone help me with this please?

As the title states. At least half the time when you try right-click and use the "Copy" function, the option is greyed out. If you try to Ctrl+Shift+C, it opens dev tools! This happens on multiple systems that I have that are based on Debian/Ubuntu. So basically, copy functionality is broken for Firefox Linux users...

When I save new bookmarks I can't find them to open them. The list of folders I see in the "Choose . . ." selection is different from the list of folders l see when trying to open a bookmark. The bookmarks seem to be saving in one list but opening from a different list. How do I replace the list Firefox opens bookmarks from with the list the new bookmarks are saved in?

Hi there. I use mailjet for sending email newsletters and campaigns. The images that i was uploading into the mailjet templates where displaying fine both on mailjet and when sent to mozilla firefox users.

The problem is that for 10 days now; when i upload images in mailjet and sending newsletters; the images are not displaying in mozilla. In contrast, when i use chrome everything displays fine, both mailjet and email accounts.

I had a long chat history with mailjet support and they requested to follow these instructions to fix this issue first: https://documentation.mailjet.com/hc/en-us/articles/360058211453-Why-are-my-images-not-displayed-missing-in-the-Email-Editor I did this but i had no success so they requested me to use chrome instead of mozilla. But that is not the solution of the problem because this must address all different browser users.

Can you please help me on this?

Thank you,

Trying to stream shows on Firefox and video does not start / errors out. Philo returns with this error: Philo is having trouble streaming this content.

[Error code: pf-1.5-5bb2f]

Paramount+ Also freezes up and returns error message. As does Amazon Prime.

Adblockers disabled. Youtube is fine.

Tried refreshing Firefox / renistalling but same error. Prefer to use Firefox as default browser but having to go to Google to stream shows.

Debating rolling back a version but it was working fine the other day but could have had an update and didn't notice and now streaming is erroring out.

Suggestions? Thanks.
