Can you help me, please?

Firefox 148.0.2

After the last update Cabela's and Bass Pro websites are blocked, won't connect. Teva has been blocked for over a year, and I can't find a page on here where you can instigate a trouble ticket.

Firefox has been a great browser until lately, I'm disappointed guys!

When a generic Search is done or even if one has Search engines under Settings, Wikipedia comes upo but not Grokipedia which is very good and getting better and better.

Hi, I'm running FF 149.0 (64-bit) on Windows 11. I've used profiles for a while now and on several occassions I've "lost profiles". Currently I have three profiles which I set up and edited the icon and colour associated with each. When I launch FF I see the Profile Manager and can select any of the three and I can create a new profile which shows here. However, once in any one of the FF profiles I don't see the others - by which I mean that when I go via the hamburger lines top right and click on the current profile, the 'other profiles' section is blank. I also cannot edit the profile from using the edit pencil top right (after clicking the hamburger lines and clicking on the current profile), it takes me to about:editprofile but the page is completely blank. Confusingly, if I go to about:profiles I see two profiles, neither of which shows up in the Profile Manager! I'm going round in circles trying to understand where to edit my exisitng profiles and make sense of the five profiles that don't all show up in the same place!

1. See Image #1: click on the link, and get this: 2. See Image #2.

So am I to conclude that somehow now mozilla.org is considered a "blocked site" . . . ?

Solution? Thank you

Since the update to Firefox a few days ago, I am no longer able to view PDFs in the browser. They still open, but they show up as blank pages. Is there a way to fix this or to revert back to the previous version of FF?

Thanks.

Hi everyone,

I’ve been experiencing performance issues while using Mozilla Firefox, especially when working with browser-based tools that handle file processing.

When I try to upload or process larger files (like PDFs), I notice the following:

• Firefox becomes slow or laggy • The tab sometimes freezes temporarily • File processing either takes too long or doesn’t complete • Occasionally I get a “page unresponsive” message

For testing, I used an online tool: [ONLINE EDITOR]

The issue seems more noticeable with larger files or when multiple tabs are open.

What I’ve tried:

• Restarting Firefox • Clearing cache and cookies • Disabling extensions • Testing in Troubleshoot Mode • Updating Firefox to the latest version

The same tasks seem to work slightly better in other browsers, so I’m wondering if this is related to Firefox performance or settings.

Question:

Is there any way to improve Firefox performance for heavy browser-based tasks like file processing? Are there specific settings I should adjust?

Thanks in advance!

is there a way to revert the changes that have been made on ver 149 regarding the scrolling? I'm trying to scroll some really long sites and when I just touch either my magic mouse or my macbook trackpad scrolling jumps to the end. Up to version 148.02 there was no problem. I've check it on 2 machines with macos sequoia and the problem is valid.

I upgraded to a new Surface Pro 12 and now when I launch Firefox it won't open my previous tabs and windows even though I've checked the box "open the previous windows and tabs" under the General/Start Setup. On my previous Surface Pro 3, I never had an issue with this. Am I doing something wrong..? Also when I click on the time in the lower right task bar, it would open the time plus a calendar. Now with the Pro 12 I get the time and a notifications window and no calendar. Is there a way to change Firefox to the way it was on my old Pro 3..?

I just got a new laptop and installed Firefox 149 on it, but I can't get it looking and working like I want it to. It syncs with my desktop Firefox for my bookmarks and history, but the Bookmark Toolbar is in the wrong place, above the address and menu bar.

Most annoying is that I can't see my tabs......I can scroll through them with Ctl-Tab, but I can't see them laid out at the top of the screen, and I can't manually choose or close any tab. My bookmark toolbar looks like where I expect the tabs to be.......I thought that Firefox was automatically opening all the bookmarks in my toolbar into tabs, but if that were the case I would scroll through them with Ctl-Tab, which I cannot. That appears to be the toolbar, not open tabs.

So......the toolbar is above the menu bar, not below it, and my tabs aren't visible. My bookmark toolbar setting is set to "always show",

Man hatte mir eine neue FAssung von firefox eingespielt - firefox VPN. Danach waren meine Passwörter, die Chronik und verschwunden und eine veraltete Lesezeichen-Datei noch vorhanden. Wie komme ich an meine ursprünglichen Daten? Wo liegen diese?

I tried unchecking and rechecking all start settings. When I close Firefox, it asks if I want to close all tabs - the only option is to cancel, leaving Firefox open, or Yes, which would close all my tabs and not reopen the tabs on startup.

My recent history is also missing.

My URLs safeeenergyanalyst.org and safeeenergyanalyst.com do not redirect to https://russlowes.wordpress.com/blog/ on Firefox, but do on Chrome and Edge. I cannot figure this out, and have contacted GoDaddy and they say it is a Firefox issue.
