A.) Now is not the time to pose as a sycophant this is serious business.
B.) I (we) have been advised of beta.
C.) It is not uncommon for company's to keep their product(s) in Beta for many, many, many months and more than a YEAR in fact.
D.) Beta software is NOT TRUSTWORTHY OR RELIABLE WHICH IS WHY IT IS CALLED BETA.
E.) Bugs in Beta software can and have wiped out all passwords and the company such as LastPass says "Whoopsie daisy" please read the hold harmless agreement you agreed to when installing our software.
F.) This link  CLEARLY states LastPass announced the WebExtension "SEVERAL MONTHS AGO."
G.) As I stated I have no hands-on developing a WebExtension HOWEVER I have been developing web apps DAY ONE since the mid 1990s and know from experience WE ARE BEING SPOOFED because it should not take months to develop a WebExtension. I dare say other experienced software developers would tend to agree. WHY DO YOU THINK THEY ARE TELLING US TO USE A DIFFERENT BROWSER? I remind all that Mozilla has the best documentation in the business bar none and a serious timely update release cycle which is why it is chosen so frequently by web developers who have serious work to get done. My apology to shout but the facts are what they are and shouting is the only way to help the deniers HEAR SOMETHING IS GOING ON HERE. SOMETHING THAT IS NOT RIGHT. SOMETHING THAT SMELLS.
H.) That "something" I allude to is I suspect based on my experience and the apparent fact that LastPass probably has an incompetent mickey mouse project manager controlling the development of the WebExtension for FireFox browsers. He/She is likely shining some shoes and kissing posteriors and will not release the WebExtension for FireFox browsers until the development team that does the real work also finishes their binary as referenced at  so He/She Mr/Ms Incompetent can play the hero internally while the rest of us are being fed his/her ca-ca de toro.
He/She Mr/Ms Incompetent Project Manager brings shame on the developers that actually do the work and must answer to a boob. LastPass users hear me out this is the real world and how company's products lose their credibility within and in the marketplace.
I.) If you are willing to risk losing all of your passwords I close in asking two things
1) Ask yourself why the page at  asks you to debug the Beta and remember this IS AT YOUR RISK OF YOUR MOST VALUABLE DATA ASSETS
2) Go along to get along sycophants never affect positive change. Nothing personal jpenney84 but we users of LastPast have to put it all on the line as I am telling the company to fish or cut bait and get the WebExtension debugged and released as a reliable extension.
I (we) know LastPass developers can. So just DO IT AND STOP WITH THE MARKETING BULLSHITTING. PLEASE.

 Our current binary installer cannot talk to the beta WebExtension yet, so features requiring the binary component (like handling attachments) are currently disabled. You can still use those features in other browsers.
P.S. For those who may not understand; the WebExtension API has been developed so vendors can write one extension that runs in all browsers that support the WebExtension API. This means by default and by specification a WebExtension that runs in Chrome or another supporting browser is supposed to run in FireFox which supports the WebExtenstion API. More food for thought about how we are being SPOOFED and why I believe the release of the WebExtension that runs in Firefox is purposefully being held back so it can be released when the binary is completed.
SO WE MUST VIGOROUSLY ASK WHO AND WHAT DOES LASTPASS REALLY CARE ABOUT WHEN THE BINARY CAN COME LATER WITHOUT CONFLICT WITH THE WEBEXTENSION?
