I've been using Spanish (Mexico) dictionary for a few years as my default spell checking dictionary. However, it lacks a lot of common words and local idioms that I use everyday.

How can I create a new dictionary for Spanish (Colombia), or contribute to the Mexican one? I can't find a Github repo with the project.

After installing Firefox Version 87.0 today, I haven't been able to open the application. Each time I try I get the following error message, "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I have tried both running the installer again to fix it and downloading a new copy of the installer and running it, neither of which solved the issue.

I found a previous thread from 2018 detailing the same issue (wherein the chosen solution was to make sure that your firewall wasn't blocking firefox's access to the internet) however;

A) I can't even start the firefox application, let alone see if it can access the internet. B) I tried making my antivirus application ignore it (Malwarebytes), but when I tried to do so it said I didn't have permissions to access the file.

To be clear mine is the ONLY account on the computer, and is the admin account as a result. My pc is running on Windows 7 64 bit in case that is relevant (though I didn't see anything in the update notes to suggest that they're ending support for Windows 7 just yet).

Hello, How do I permit Calibre to use IndexedDB storage in Firefox? I am running Firefox 87.0 on Windows 10. Both are fully updated as of the time of this writing (26 March 2021). In Calibre 5.13.0, I enable "Sharing over the net," then I "Start server," and then I "Test server." Calibre opens a tab in Firefox but returns the following error message: "Error: Could not initialize database You must allow calibre to use IndexedDB storage in your browser to read books" I cannot figure out how to enable IndexedDB storage for Firefox. Thank you in advance for your help, Eric

HI I am a trainer and web developper and in all trainings and as a designer I am using the Firefox Inspector. This morning, suddenly the menu under EXTRAS is not showing anymore the "INSPECTOR". Don't know what has changed! I installed Firefox again, no change! I know, that I can still activate the inspector via OPTION COMMAND C but this is not very intuitive for my trainings! See screenshot: What happened? Any ideas?

Thank you in advance! Mathias Will

I had to clear History and Cookies on my desktop to get an online purchase done. I was able to add my passwords for every site bar one (afl.com.au). It just won't accept my password despite changing it. Works fine in Brave and Chrome. Also fine on my laptop (didn't clear anything there). Any help sincerely appreciated.

I had stopped using Firefox due to the lack of being able to preview pictures or attachments in gmail. I started back to using it and see it still the same thing! A panel opens up asking me either to choose how to open it or top save it. Obviously if its a .jpg I want to preview it, then decide what I want to do with it. How do I fix this so I can just preview quickly?

Hello dear community,

I recently switched to a dual boot system and got Ubuntu 20.04.1. If I want to watch Netflix for example I cannot because of DRM settings (at least the pop-up of Firefox says so). Other video and audio content is working fine so far. The guidelines on what to do to solve the problem like this

https://support.mozilla.org/en-US/kb/enable-drm?as=u&utm_source=inproduct

won't work unfortunately. Does someone have any other idea what to possibly do?

Thanks a lot for your help! -Jo

Hi, .html files which I've downloaded onto my hard drive as complete web pages won't work if they are moved to another directory. Is there a work-around for this ? Thanks in advance. afk

having troubles with Comcast email obviously using FF 87.0 (64bit) after hours on the phone and the problem being elevated to what Xfinity said level 4 ....they tell me it is in my settings.......I can login fine in private browser.....lost as to why I cannot in my normal browsing mode....help

I'm trying to find an answer to a question about Thunderbird. I type it into the "Find help..." box. I get a page with a small number (maybe 10?) results. The first page of results doesn't seem to help. Neither do the next five pages. I suggest letting users choose the number of results per page. Being forced to click the "next" link on every page is slow and tedious. Hitting the "Page down" key on my keyboard is much faster, partly because I don't have to use the mouse.

I visit sites which require password changes on a regular basis and each time I do this I save the login details in Firefox.

Now I have sites where over 20 login options are displayed.

I want to delete all of the expired login combinations but when I try to manage the passwords I only have the latest (correct) combination displayed.

How do I prune my password lists to remove obsolete details but retain the current ones?

Can this be done by exporting the list, editing it externally and then re-importing? I don't want to try and then lose this useful feature.

I am trying to minimize Firefox, but the minimize icon in the upper right-hand corner is missing. I am still able to close Firefox using the 'X' in the upper right corner of the window, but I am unable to minimize or restore. All other applications still have these icons available.

Do Firefox's title bar buttons change depending on custom Windows 10 themes (I hope that made sense)? Whenever I choose a custom theme (from DeviantArt) those buttons look out of place, any way to fix this? I only have this problem with FF The theme is this -> https://www.deviantart.com/kdr3w/art/Gray-Dark-807271550

EMAIL DISPLAY IN GMAIL: Hello. All of my emails open the first page okay, but an increasing number of action pages in emails do not open. Those pages contain forms to fill out, petitions to sign, and donations to make. This problem began in late February/early March (FF 86&87).

The tech support at EveryAction.com said she thought they need Javascript to open, but I couldn't find any setting or add-on in FF to enable/disable Javascript. I don't know why all of their action pages have been opening fine for years--maybe it's related to FF's new versions. I tried adding Policy Control because it supposedly enables/disables Javascript but it didn't solve my problem.

The tech support at Earth Justice wrote this in response to my report about their action pages not displaying: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) Gecko/20100101 Firefox/87.0; https://earthjustice.org/action/investigate-troubling-payments-that-threaten-the-florida-panther?contactdata=8D8RgJTCUXwiDCjeWPHh7wQ1fwDy7YSqjRoUFBMLj9iH2tXUofJiQ1CKU%2fIhkHfdjY8KsFkiYme4BhD4yp%2bpJ9S13ALo6NdUs4CtwLA2KaAhIZ0GP2%2bWq9ZUYNwtkHNEKC%2bxUF4VNRJ1XirXG00WayYuwLGnnHVzRWtCwf3s%2fqtR64TlcMwKx0w2e3AyPLspJ8xDw1TQNs%2fSBpWztf%2fNBkvDKFTrC6fsKAvY54zt13IfVVPcfU%2byEdneTMzDaYIN&ms=email&utm_source=crm&utm_medium=email&utm_term=action&utm_campaign=2102_Action_Panthers_Haaland&%3butm_content=HTMLTakeActionButton1&emci=5a0f473e-c881-eb11-85aa-00155d43c992&emdi=01870d6d-d68b-eb11-85aa-00155d43c992&ceid=962627 "We are still investigating this problem, but it appears to be concentrated among Firefox users. We do know that our EveryAction forms require Javascript to be enabled, so if it’s disabled and you’re able to enable it that might work and would be helpful to our efforts to sort this out. Let us know if you’re able to get that to work, and thank you for your patience."

I would be very grateful for your help in solving this problem. I'm sure there are other users out there with same problem. Thank you. --Sincerely, Bo Bergstrom.

I am unable to download anything using Firefox. I have tried everything listed in this article: https://support.mozilla.org/en-US/kb/cant-download-or-save-files

Nothing has worked; starting in Safe Mode; clearing my cache; disabling all addons; disabling my firewall; disabling my antivirus; even reinstalling.

I can download using other browsers just fine, but not Firefox for a reason I cannot figure out.

The "View History Sidebar" command is missing from the History menu after updating to Firefox 87. Is this a bug or was it intentional? The Bookmarks menu still has the "View Bookmarks Sidebar" command.

While I found it possible to work around the issue via Customize and adding the "Sidebars" control, this is quite unintuitive and awkward to have to use two different buttons in order to access your history. (IMHO, the History menu should just show the full history to remove the need for the sidebar, but that's a separate discussion.)
