Firefox Support Forum

I have tried to remove from doc to pdf from myway several times. It is gone for a day or two but then comes back having taken over my firefox homepage. Don't trust this page at all. Have gone through the procedure described in the help section but still returns. Please help!

Did Firefox Support Forum go back to its previous version within the last few hours, or did it just happen to me? This can be deleted once I get an answer, but I'm asking, because I had a long-running thread on the other forum and need to know if I need to repost my problem I was working on. For instance, this was my most recent crash:

bp-912166d8-b038-40e3-8f8a-9b8860170419

I have gone around and around on this site trying to fix the fact that everything hangs up constantly. It's been one day and it's so far been a miserable experience. Why can't you speak with anyone. Not all of us are that tech savvy it's horrible.

After updating Windows 10 Pro x64 to the Creator's Update any video, when put to fullscreen, starts to lag. I've tried Firefox portable and the problem still persists. I have Chrome as well, but the problem does not occur. I've tried reinstallation and both 32 and 64 bit versions, but no luck.

Any help is appreciated!

Thanks!

The initial opening of of Firefox goes to the proper home page. When I go to the next tab it goes to an address and page that is not the same as the one I have built. It goes to a Package Tracking page. Probably phishing.

How do I solve this problem.

I posted this question before & got some answers (from JSherr2000 I think was the username). Anyhow, I'm closer to finding an answer. With my customized theme in Windows 10, the dropdown menus became black & unreadable as I scrolled down them with my mouse. Apparently, when I use an Aero theme, this doesn't happen. Trouble is, I don't like the Aero theme & I can't make as many visual modifications with a standard theme. I'm not sure why this only happens with Firefox (although I haven't installed Thunderbird yet on Windows 10).

I should mention that I'm posting this from my Windows XP machine & I have the lastest 64-bit version of Firefox installed on my Windows 10 machine.

The sent folder is not visible but I still can click on the line and the message still can be read in the message pane. But, the message cannot be open if I double click on the message.

I have standard desktop Firefox 52.0.2 installed, but this morning the update pushed to me is labeled 52.0.2esr.

Why was an ESR update pushed out to me when I have the standard desktop release installed?

I have no plugins installed on my computer. No Java, no Flash, no Silverlight.

I've recently been having issues where Roll20 (an online tabletop game app) is very slow and laggy. It works absolutely perfectly in Chrome, which I don't use at all other than for trying this out. So, to troubleshoot this, I did the "refresh firefox" option which ported over my previous saved passwords and bookmarks. It still ran poorly. After that, I tried CTRL+SHIFT+DEL to delete just about everything there. Still no dice, and now Firefox encounters random issues such as seemingly random freezing/hanging, or having high CPU usage/1mil K 'memory' in Task Manager, when only having like 3-4 tabs open and listening to music on YouTube in one of them. I'm unsure what the problem is, exactly. I don't think it should be hardware-related as it only started occurring after doing troubleshooting in FF. One thing that raises a flag for me is Malwarebytes AdwCleaner advises my Firefox prefs.js is a threat. Could this be related?

since the last upgrade a couple of days ago, each time I open firefox it presents me with a window which has an address resource://support-at-lastpass-dot-com-Mozilla Firefox in the header and is otherwise blank. Ive recently picked up the latest upgrade for the last pass extension to version 4.1.46a

I have a MAC and purchased Roboform as a software. I have removed the software and every time I open Firefox, the home page for Roboform opens and not to the home page i have selected in my preferences. I need to know how to change this.

I have changed my search options at least ten times, restarted the computer, yet "Radiocasa" continues to show up. I hate that search engine. This is why I will not be using Firefox as my browser.

Using Java you take so out, that no chance is there, to use it. But some programs, very important for me, use Java. Why don't you give any user the chance to use it or not. It's my problem, not yours. But no, you make it like Microsoft, eat or die. So good bye Firefox. I hope, some outher started a new browser, in where I can say, what I want and what not.

I'm currently using KDE Plasma on Archlinux and Firefox windows are very laggy when maximized. I have a 4K screen and running Firefox at full 4K causes scrolling to be very choppy and makes YouTube almost unresponsive. If I make the window smaller (about a quarter of the screen or the size of typical 1080p), it speeds up and works normally. I've tried the nightly build, Icecat, and Waterfox and none of them have made any difference.

I use a AMD Radeon R9 Fury X GPU and have the latest version of xf86-video-amdgpu installed and have hardware acceleration enabled in Firefox settings.

EDIT: I've now tried Firefox in Cinnamon Desktop as well as KDE Plasma and they are both equally laggy.

Ok, this has been happening for over a year now. I have tried resetting Firefox, reinstalling it, running it 100% clean without any add-ons and whatsoever. None of these fixed my issue. Whenever I find myself using Firefox for more than a day or so, without closing it, the problems start to occur. First hours of the problem occurring, it starts to freeze from time to time for 1-2 secs, after that it freezes 1-2 times for 10+ secs and finally it just hangs until I force close it. I think it is caused by videos mostly, because whenever the crash happens, I'm browsing a website with a video. Around 80% of the final unending hang happens whenever I play a video. Whenever I go to force-close the browser, I always find it at 30+ CPU usage. Since I am unable to create a Firefox log or some sort of detailed information, I am uploading an image and list (https://pastebin.com/KpVAYjhD) of firefox handles (because GetHandleVerifier function seemed most suspicious and could be related) that I think might help you with debugging the issue.

When I search for something on the internet using Firefox, Bing most times comes up as the search engine and I'm trying to get rid of Bing as a search engine. I have changed the 'Search' preferences in Firefox but Bing still shows up?

The warning message is appearing more frequently and seriously affects my use of the computer. Clicking on 'Stop it or Wait' removes the message but it comes back sometimes in only a few seonds.
