Oh you mean for FF mobile. If the install doesn't work then I don't think the script will work. This was meant for computers, not phones. You can always try Tampermonkey for Android
I use them exclusively on desktop, as I find doing OPR on a phone very cumbersome. That said, there appears to be a tampermonkey app for Android. This should theoretically, allow you to install and run the script on mobile. I am not sure if the script's author wrote this to work on the mobile platform, and I don't have an Android to test on.

Actually I believe it would work on both Chrome and Firefox mobile browsers. Obviously not ideal as it's not in-ap, but better than nothing for people who only have access to mobile.
Greasemonkey(Firefox)
Tampermonkey (Chrome)
Ha! Not a dumb question, but I am not sure.
If you're asking if it can interface with the YahooFF app, then no it can't.
It was strictly designed with the Chrome Desktop in mind. TamperMonkey does have a mobile application, but I've never used it. So, I would say it's a MAYBE if you're loading it on your phone's Chrome browser. Here's some information on tampermonkey's mobile app: https://play.google.com/store/apps/details?id=net.biniok.tampermonkey&hl=en
Okay I can't help with Destiel like at all, but I still want to help. I just recently (yeah only recently bc I'm stupid) worked like crazy tailoring my AO3 search results experience via userscripts.
I'm gonna assume you use either chrome or firefox. Download the extension Tampermonkey here for chrome or here for firefox.
Now go and install AO3 Savior. Once you do, click the tampermonkey extension icon, click 'dashboard', then click 'ao3 savior' and you'll get the script configuration text that's super self-explanatory.
NOW - and this is the super fun part - do an AO3 works search for something broad that you like, such as "characters: castiel, dean winchester" & "additional tags: hurt/comfort" & "Sort by: word count."
You'll get a shit ton of results that you don't want. Find the tags that you least appreciate in your unwanted results, then go into AO3 savior's configuration text and add them to the tag blacklist so for example:
tagBlacklist: ['wincest', 'sam winchester/dean winchester', 'dean winchester/sam winchester'] // excludes works with a tag that matches at least one term. Use * for wildcard
Edit: just fyi "use * for wildcard" -- wildcard means any form of the word, so for example if you write "lemon*" then the following words will get removed: "lemon, lemony, lemons, lemonish, lemon!kink, lemon fic" etc.
Then click the save icon in the tampermonkey script & refresh the AO3 search page.
Do this over and over again until you start finding some fucking gems that seem right down your alley!
Same thing only less complicated with AO3 Crossover Savior, where you can filter any/all results with too many fandoms in the fic.
More info in /r/AO3's sidebar :)
Also there's our Guide to Fanfiction but also there's our list of SPN Fanfiction Databases that might help ya out (if you really have exhausted all the 70k+ Destiel fics on AO3 lol :)
There's also Tampermonkey for Android and an earlier implementation called OilCan. You'll have to use this script. No guarantees on it working / not having memory issues as well.
I haven't tested it but try this: https://play.google.com/store/apps/details?id=net.biniok.tampermonkey
I also suspect you would need to plug your phone in and keep it from shutting off.
It will work in the Android Tampermonkey app. https://play.google.com/store/apps/details?id=net.biniok.tampermonkey
Install Tampermonkey if you haven't already
Add the Gecko Tools userscript to it
And then add one of the themes from this page by dragging and dropping the files onto the screen when you have tagpro up. If it all works, you should see "files accepted" at the bottom.
