Fóram Tacaíochta Firefox

I've been using Firefox for quite a while, but it has recently begun opening every previously open tab when I restart a session. I only want the tabs I selected for my home page to open. I've tried going to the options and selecting "Show a blank page" on startup, but even that is ignored and all of the prior tabs open on each new start. I've rebooted the computer and restarted Firefox, but the problem remains.

When i upgraded to windows 8.1 the arrows with the bookmark folders became too large and i cant use 100% DPI as its too small even with adjustments and visually depressing - its the same on all my laptops and PC.s - it wasn't this way with windows 8 - its obviously something Microsoft have done but can you fix it - i have seen this problem before can you help - anything other than 100% DPI causes the arrows to be huge - screen resolution has no relationship to the problem - thanking you.

Have a look at the screenshot. Sometimes the navigation arrows come in strange shapes and sizes. Sometimes the sizes are completely disproportionate.

Just open up nbcnews.com, click any article, use the back button's drop down menu to see that there is only one page to go back to, the nbc home page. Now scroll down to the bottom of the article and now check the back button again. It's full of history for this single page. So now getting back to the nbc home page requires lots of clicks. So Annoying.

I have already tried a clean unistall and downloading the program anew. I have made sure the firewall (Defender) allows Firefox. Firefox worked for two months on my new computer with Windows 8 before I started having problems. I was hoping 8.1 would fix the problem, but no such luck.

Couple days ago I've received my new PC and migrated all important data from the old one using a special W8 tool. I've also installed Thunderbird and FF anew, and migrated their setting using tools recommended here (FF Sync + MozBackup). And suddenly I've lost a possibility to open any external link in FF now no matter the source (Thunderbird or any other piece of software). Now I have to copy and paste URLs manually. It's not the best solution. Old PC OS: Vista Business, new PC OS: W8.1. Thanks in advance.

Just recently gotten back into using Firefox. Have been using Chrome. Firefox has one thing that Chrome doesn't have. So I see a number of old Plugs Ins from back when. How do I delete them. I've set to Never Activate. After each Plug In shows RESEARCH. But I don't want to research...I want to delete the old ones. So where do I go from here?

When webpages are loading, or when I scroll down a page, sections of the page appear black. I can sometimes clear this black panel by rotating up and down, the mouse wheel.

I have tried switching off hardware acceleration. I have checked fonts colours (black fonts and white background) and all drivers are up to date.

I am running Windows 8.1 and FF 25.0.

I'll be browsing, and Firefox will shut down. It's usually when I click on something, but occasionally when I'm just looking at the screen. After the last crash, I reopened Firefox and all my tabs came back. This happens once a day, occasionally more. The sporadic frequency makes it hard to troubleshoot extensions.

Thank you!

I am running Win. 8.1 and had no issues with FF 24. Since upgrading to FF 25, firefox will appear closed when i close the window but the process doesn't shutdown. I have to go into Task Manager to end the process. I can then launch it again.

If you use Data Syncing then this is attempted every time you start Firefox. If you also use a Master Password then it tries to sync your passwords every time you start Firefox too. This means that every time you start Firefox it asks you for the Master Password. This is incredibly irritating.

I realize that you need to sync at the beginning of a new session but would it be possible to delay the syncing of passwords until the user actually needs to use a password (i.e. the default behavior for using a Master Password without syncing). After all, it doesn't matter if the passwords are not synchronized if they are not being used. When a password is actually required then Master Password could be requested and the stored passwords could be synchronized if the correct Master Password is supplied.

I have 64 bit Windows 8.1. I have activated Lightbeam but I cannot see any data about the sites I have visited. It tells me I haven't visited any, which is not true. What should I do?

I recently downloaded FF 25.0 on a new computer (Samsung Series 9) and web pages don't render correctly though I used default settings and have same extensions (all in one sidebar and list it). I asked our tech person and he said "Your CSS isn't loading. Try clearing your cache and restarting your browser". This worked but now I find I have to repeatedly do it as many as a few times a day, with varied websites, and once it happens, all websites won't render correctly. I don't want to have to switch to chrome, please help! Here is a screenshot.

The message appears in a box, with the heading called Security Warning. Then reads:

Do you want to run this application? An unsigned application from the location below is requesting permission to run. Locations: http://xxx.xx.xx.xxx Running unsigned applications like this will be blocked in a future release because it is potentially unsafe and a security risk. Select the box below, then click run to start the application.

The issue started yesterday on 11/8/13. I would click on a Youtube video and it will play perfectly throughout the entire length of the video. Once it is done however, when I click the replay button, the video returns to the 0:00 play mark, but the video won't play. I try moving it to the different intervals of the video, for example , maybe 1:20 mark or 2:24 mark, etc, and it'll just return to the 0:00 mark of the video and won't play at all. To test if this was a computer malfunction or just a Firefox one, I tried doing the same thing on my Internet Explorer browser, and Youtube works perfectly fine on it, replay or otherwise, so I narrowed it down to a Firefox issue on my computer. Is there a way to fix this issue?
