Signon to GMAIL or Youtube Premium inside Firefox both return an error about using an unsecure browser. No issue with Chrome or Edge.

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

This is the error message.

I have tried resending numerous times since last night with the same result.

Version 122.0.1 Firefox Release February 6, 2024

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?

Something went wrong w/ the mouse, some of my tags disappeared & wasn't able to recover them via Ctrl+Z, so I decided to perform my 1st [Restore] (never had to do 1 before), since I had just recently done an [Export Bookmarks] & a [Backup]. Everything seems to have gone Ok, except that for every tag, all of the bookmarks listed under the [Name] column are duplicated. When I right-click & [Show In Folder], they both show in the same folder. When going onto their folder, they are only shown once, so there are no duplicates there. When I attempt to [Delete] 1 of the 2 duplicate entries they both get [Deleted], so I can only conclude that they are 1 in the same. But the question remains, "How can I fix this duplicate condition?"

Another related & interesting behavior is that, from any bookmark folder where you can clearly see there are no duplicated bookmarks, when you do a [Search] from the top-right-hand search-box, the "results" are also "duplicated", although you might need to sort them by clicking on the [Name] column control. So, I can go to any bookmark folder & clearly see that there are no duplicate bookmarks, but when you do a [Search], that's when you get duplicate entries. That leads me to believe that this is the result of the [Search] function, & thus for some odd reason the [Search] is generating "duplicate entries". And then perhaps, both the [Tag]s & the [Search] function are related.

Also, this "duplication" does not happen on newer added bookmarks, after the [Restore] was executed, & it's only a phenomenon that affects those bookmarks that were saved by the Bookmarks' Library [Backup] function, & thus this anomaly was introduced by the [Backup].

Actually, I just realized the problem is more complicated than I thought. The reason any search results in "duplicate bookmarks" is because there are 2 sets of folders, 1 set above the other, & if you don't scroll down all the way you won't see it. So that's why there are actually "2 Sets Of Bookmarks", because there are "2 Sets Of Folders", 1 above the other. The problem is that when you delete any "Duplicate Bookmark" you delete them both, & not just 1 of the 2 bookmarks.

I wonder if it would work, to "Delete All Bookmarks" & then do a [Restore]?

Could "Mozilla Support" answer that?

Don't know why every time I attempt to [Post A Reply] & get an "Error",... So I'm going to post my reply right here,...

Fix: (2024-02-19) Of course, I did some testing before I concluded what was the best approach, but since I noticed all of the "Bookmarks Folders" were duplicated under [Bookmarks Menu], an easy fix is to go to the "bottom duplicated folder", right on top of the [Other Bookmarks] folder, & "Select It" (by clicking on it) & [Delete] it (w/ the [Delete] key on your keyboard). Do this 1 by 1, until you reach the "bottom folder" of the bookmarks' folder you certainly don't want to delete. Close Firefox & then reopen it - to make sure Firefox takes care of any garbage-collection. Then do your Bookmarks' Library [Export Bookmarks To HTML] followed by a [Backup], & you are good to go.

Actually, I don't know what introduced the error. Don't know if it was Firefox's [Restore] function, or it could have been me (by accident) w/ some "unnoticed & unexpected" move of the mouse/trackball, which accidentally duplicated all of the folders w/o me noticing, & that is why all of the "Bookmarks" were "duplicated".

Happy Firefox Browsing,...

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.

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

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,

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 want to disable the "language-aware word selection when double-clicking on text" feature that shipped in 122.0 (https://www.mozilla.org/en-US/firefox/122.0/releasenotes/)

This new feature is cool, but it has actually slowed down the speed at which I select text. Originally, I could double-click to select an entire sentence, but now a double-click only selects a single word.

It would be great if there was a way to disable this feature for a specific language.

Thank you.

Often I open a new tab & it's bugged. (It displays fine but the "right click" menu doesn't work.)

The fix is right clicking the tab itself (at the very top) & then clicking "reload tab".

Is there a hotkey for this instead? I hoped ^{f5} would work (control f5) but it didn't seem to.

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.

Hello, as of the last week, my Firefox wont open any Excel 365 scripts, pop-up windows are enabled, I have tried with my Firefox account in multiple different Windows 10 PCs - none worked, there is no problem in other browsers.

What could be the reason?

Thank you

I am running v122.0.1 on a Mac and since the last update if I open a Facebook Messenger message which pops up at the bottom of the screen clicking the minimise or close doesn't do anything and the message stays on screen The only way to get it to close is to log out of Facebook and then log back in again. Is this a bug in this release?

I have the HTTP_PROXY, HTTPS_PROXY and FTP_PROXY (and their lowercase counterparts) exported and then the firefox binary is started from the shell script. The settings in firefox say it will 'Use system proxy settings'. Nevertheless I do not see the proxy being used as I can not access the web pages that need the proxy. The 'about:config' also does not show that firefox picked up any proxy related information from the shell environment.

I know the proxy address is correct because if I use brave browser instead of firefox (same shell script that launches brave) I can reach the web pages behind the proxy as expected.

Today a website told me I needed to enable JavaScript in order to continue, despite the fact that it is enabled. At first, when I received this message, I turned off the "NoScript" extension and tried again, but the website still gave me that same message. So then I went to the about:config page. and it showed that JavaScript is enabled because it showed a value of "true". This sort of thing has happened more than once in the past. I'm forced to go to another browser such Microsoft Edge or Chrome, where I do not encounter this problem. Why is this happening in Firefox, and what can I do about it? My operating system is Windows 10 Professional, and if you need any other details, please let me know. I will appreciate your assistance.

I have been trying to solve this problem on and off for about a year now, but 99.99% of the time I try to access https://en.wiktionary.org/ , I get the following error: Secure Connection Failed An error occured during a connection to en.wikitionary.org PR_END_OF_FILE ERROR Error code: PR_END_OF_FILE_ERROR

I have NEVER gotten this error message for any other website. And the strangest thing? Sometimes I CAN access Wikitionary with zero problems, but this phenomena tends to only happen when I attempt to access the website very late at night or really early in the morning. I cannot think of a single thing I have done differently when this happens.

By the way, I am able to access Wikitionary from Microsoft Edge just fine, it is ONLY Firefox where I have this problem.
