Φόρουμ υποστήριξης - Firefox

I get the following message when going online with Firefox: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I've followed all the prompts to restart the computer, refresh the computer, delete the favicons.sqlite and places.sqlite and it won't allow me to delete them. This happened yesterday as well. Yesterday I could delete those files and everything was restored. But today I can't get it to work.

Hello,

I like using Firefox browser every day. After installing and running Avast antivirus protection (program version : 24.3.6108 (build 24.3.8975.832)), Avast notification always show this message every time I start up Firefox : please check the uploaded images : FPA Scam.jpg.

I already checked the extenstion, the Settings, and the Advance Settings of Firefox browser. I'd like to know if there is any parameter related to engine.forexpeacearmy.com and it is enabled. Unfortunately, I can't found any related parameters.

So, I decide to contact Firefox support to find out what happen to my Firefox browser, why it always call the forexpeacearmy site at the start up, and finally I want to remove it. Because I'm affraid it could be some kind of trojans / malwares and put my laptop into risks.

Kindly need your advise. Thank you.

Kind regards, Gideon

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

My IDM extension no longer seems to be the default downloader. Downloads now come via the native Windows (8.1) downloader. Can you suggest any way of resolving this issue?

I searched for an official portable version of firefox and one of the first results was this https://support.mozilla.org/en-US/questions/1247235 anyways this seems dissapointing since he says we should only download from official sources and at the same time there is no official portable version, can i be honest.. this sucks. You know time passed since that thread was created (3 years...) but still no offfical version, why?

So it seems to most known source for firefox portable is this site: https://portableapps.com/apps/internet/firefox_portable I know you don't represent this website but still i have to ask how secure is it?

Also, how are chances mozilla will work on a portable official version? any plans?

I recently had to reinstall firefox due to a few issues. Before the reinstall, when I opened a new tab it would open as my home page. After I reinstalled it, I was able to set up my homepage URL but there is no option for new tabs to open wth the same page. The only options for new tabs are blank page or the default firefox homepage. This was never an issue before the reinstall.

How do I fix this? Has the option been moved somewhere else?

"Sorry, the video player failed to load.(Error Code: 101104)" - this error message happens on some sites but not others. I believe there are more than one type of streaming transmission but do not know how to determine which is failing. For example, the streaming daily report on Democracynow.org fails while the reports on http://www.bbc.com/news/video_and_audio/international does not. This has been a problem for weeks now. I view both of these sites every day but must now use Microsoft Edge (ugh) to view democracynow.org.

Hi, I just bought a new Windows 11 Ideapad laptop and installed Firefox 109.

The laptop display has a resolution of 2560x1600. My external monitor has a resolution of 1920x1200, so both are 16:10.

If I duplicate displays and just use the external monitor, which is what I have always done, Firefox renders all text as very blotchy, like a printer that is running out of ink.

Edge looks fine on the external monitor. I installed Chrome and it also looks fine.

I have a attached some sample images. I used my phone to take photos of the monitor. I noticed that if I used the Windows Snipping Tool or FF's built-in Take Screenshot that the image was darker and clearer in the selection box than when it's normally displayed.

I read a lot of comments on forums about various setting changes to try in about:config under gfx.font_rendering. Many folks say that has helped them. I tried lots of those setting changes, but none of them helped.

Also in those forums some folks said there was a change in rendering from FF 108 to 109, so I installed FF 108 but it looks no better.

Since I normally just use the external monitor, when I looked at the laptop, I suddenly noticed that Firefox on the laptop display looks fine.

Some online searching suggests using "Extend Display" in Windows if the laptop and external monitor resolutions do not match. I tried that and then Firefox looks fine on the external monitor. The laptop senses the different resolutions, it seems, and changes something that helps Firefox.

I prefer just using the external monitor. Duplicating the display is an option, though not my first choice. My other options are: Buy a new monitor with 2560x1600 resolution, except that I just bought this monitor recently so that's wasted money. Return the laptop since I've only had it 2 days and get one with a 1920x1200 display. I had considered one of those, but it was more expensive and opted for this one.

I'm trying to understand why this would only affect Firefox and not Edge or Chrome. Are there any ideas on that and if there is a way to remedy it?

Thanks, Ross

I have a new HP Pavilion 24 AiO PC. I want to transfer all of my browser settings, most visited sites and history from my old PC to this new PC within Firefox. Can I just Copy/Paste these settings from my old PC to the new one?

I'm on Facebook, only browser open is Fire Fox, FB freezes up and I get this "Page is slowing down Firefox, press STOP." to spped it up, what Page? I'm only on one page and its Face Book, get this when I'm on other sites too, and Other Browsers don't do this crap. Only fire fox does.

Since yesterday whenever I put a video on youtube or any other site to full screen it does not goto fullscreen, the photo shows what I mean I have already tried doing this and it didn't work Go to about:config and make sure full-screen-api.enabled is true and reset the other full-screen-api settings to default while you are there.

Videos also do goto full screen on Chrome so it must be an issue with Firefix not my laptop

The New Tab page includes some shortcuts by default, including Amazon Search (see "@amazon" in the attached picture), which I dismissed shortly after installation. (The only options are "Pin/Unpin" and "Dismiss".)

However, I want to create such shortcut for another search engine, like https://duckduckgo.com/?q=%s&iax=images&ia=images and I don't see the option - even if I set the URL to include "%s" and the name of the pinned shortcut begins with "@", as with smart keyword search and the Amazon search shortcut, respectively.

I am an advanced user and don't mind manually editing files in my profile folder (after I back it up of course).

Edit: I found a reference to it in prefs.js in my profile but changing it using user.js only caused the user_pref to disappear with no effect on the tile items. user_pref("browser.newtabpage.pinned", "[null,null,null,null,{\"url\":\"https://www.amazon.com/\",\"label\":\"@amazon\",\"searchTopSite\":true},null]");

The blocking of mixed content is stopping me from using Ebay. I can't expand photos of items or look at any a additional photos . Most importantly I can't bid. Which is VERY, VERY, VERY frustrating and annoying.

I have followed your help guide as to how to turn off this annoying feature, but they are incorrect!

When I get to the appropriate screen which say 'You are not connected securely...' the tab to turn off blocking protection for mixed content is missing. It doesn't exist! Consequently I can't tun it off and can't bid or look at photos on Ebay.

Please correct this asap please.

bold text i must get into my online bank account with bank of america using my yahoo.com sonce you are blocking it. & i cannot change it

When I press the "menu" button in the top right of the screen, nothing happens. If I hover over the button, it says "open application menu" but clicking does absolutely nothing. The same happens with the account button to the left.

What can I do to fix this?
