Firefox-Hilfeforum

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

Hyatt.com can be loaded on other browsers but not on Firefox. There is just a blank page with no error message. There is an archived thread on support.mozilla.or called "hyatt.com". The suggested solutions don't work or are too complicated. So please solve the problem. And STOP archiving threads that are still an unsolved problem! Am using Win8.1 and auto-updating Firefox.

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

I've got a legacy transformer laptop with an integrated wacom-type sensor screen. Despite all shortcomings of it's age, the laptop's got class.

The main web browser installed is Firefox ESR. In tablet mode, control was handled by the Windows - mouse-like drag'n'drop, marking, but with added scrolling gesture by swinging quickly up and down. Using it in the tablet mode is actually very practical.

Recently, after updating from 91 to 101, browser started to interpret the pen as a finger, controls became clumsy and frustrating. The only way of turning finger gestures off, parameter gestures.enable_single_finger_input described in that question (https://support.mozilla.org/en-US/questions/973974) had no visible effect. Have fallen back to 91esr, but this is obviously just a temporary solution. Is there any way to add force-disable parameter or something?

I have had 2 sites produce this error box in place of the target Web Site (See Picture). I have read previous topics about this and have followed the instructions with no positive results. FYI, clearing the web site's cookies, clearing Cache and disabling Hardware acceleration.

The first was https://www.walmart.com. After leaving a "Feedback" 2 weeks ago it appears as if they were able to fix the problem. However, the site is not as important as my Medicare PPO provider. I tried loading previous versions of Firefox, but that did not help.

In both instances the LOL "support" people's response was to try a different Browser. So, I reluctantly loaded Google Chrome and it worked perfectly. From my perspective, this eliminates everything to do with my machine setup.

Below is the sign-on URL (not unique to me). Please note that this 668 character URL has not changed for over a year. It is just Aetna's adoption of the Imperva Security Firewall. Both my Winders 8.1 and Winders 10 machines produce the identical results.

UAC notification pops up every time I try to open Firefox since last update on 5/5/22. I've deselected all options that run the program as an administrator, but it still shows up every time. I've checked that no admin is selected in both the shortcut I use and in the program itself. Any suggestions?

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'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

Hi, I spent several hours trying just to change the color of the downloads icon (thought it would take me 1 minute). First I tried to do it myself, then searched the internet. From what I found on the internet, some stuff doesn't work, some works partially and in an unexpected way, most of it is difficult to understand and modify. Finally I give up. Please, is it possible to make white the download pie and the arrow thing (when the download is finished). That's all I ask for. If possible, without using the var-- stuff, just using fill: or filter: or some other straightforward functions.

All my bookmarks have disappeared from bookmarks. I restored bookmarks in the menu folder but my bookmarks in the bookmarks toolbar are still missing. How can I get my bookmarks in my bookmarks toolbar back?

Since the last FF update (115.5esr, Windows 8.1 Pro) I keep getting the following error message when I try to access one particular website:

The page isn’t redirecting properly An error occurred during a connection to www.doordash.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have tried virtually all the solutions suggested online. I have cleared my cache, deleted cookies and site data, and I have tried to access the site using Troubleshooting mode, all to no avail. I contacted support for the particular website and they have no difficulty accessing the site with FF.

I can access the site in question with the Chrome browser, so the issue would appear to lie with Mozilla. I use this particular site frequently and would much prefer to continue to access it using it with FF, as I have done for over a year. I just installed Chrome on my Windows 8.1 Pro PC solely for the purposes of accessing this one website.

Help in resolving this issue would be greatly appreciated.

Hey !! Mozilla, I just updated ....What happened to the compact mode for Bookmarks..Now they are double spaced they take up too much room.. Bring back compact mode or I will have to find another browser that enables a compact mode. Infuriating.

I have a dozen old embedded device modules (circa 2003) which can host a web page. When I access the device through my local intranet (192.168.0.xxx), the web page displays correctly. However, when the same page is accessed through my DNS service (xxx.gotdns.org:xxxx) over the web, the Firefox INSPECT:network tool indicates that the document is type:text and displays the HTML in a text format. The first line of the HTML document is :<!DOCTYPE html>.....

These devices are non-secure information-only devices, but at least Firefox allows for HTTP: exceptions.

However, I cannot understand why Firefox treats the same content differently depending on the path. Is there a way to force Firefox to actually look at the contents of the packet and treat it accordingly?

I just tried to open a new window using File, New Window. It is GONE. I always use that. Now all I get are New Tab New Container Tab (grayed out so I can't select that) New Private window, some other stuff.

The same is true if I right click. I get: Open Link in New Tab Open Link in New Private window.

What did I do to cause these changes?
