I don't use FULL TEXT, but this isn't the first time I've heard of this sort of issue. Could you post some DDL, sample data, and the querying code you've tested so we can better assist you in resolving this issue?

We need your table DDL (CREATE TABLE statements) and some sample data to test with, please.

This pattern works well in these cases:
...and (@firstname is null or contains(firstname, @firstname))
...

Here's some code I've used. I can't take full credit for the code and apologies to whoever wrote it originally. I've had it in my "toolbox" a long time.
First the parser:
CREATE PROCEDURE [dbo].[FullTextParseSearchString]
(
@keywords VARCHAR(500) = NULL
,@proximity VARCHAR(10) = 'NEAR' -- and, or, near
,@parsedstring VARCHAR(500) OUTPUT
)
AS
BEGIN
SET CONCAT_NULL_YIELDS_NULL OFF
SET NOCOUNT ON
/*
DECLARE
@tempstring NVARCHAR(4000)
,@ParsedSearchString NVARCHAR(4000)
EXEC dbo.FullTextParseSearchString
'Red Car'
,'NEAR'
,@tempstring OUTPUT
SET @ParsedSearchString = ISNULL(@ParsedSearchString,'') + ' OR (' + @tempstring + ')'
SELECT @ParsedSearchString AS ParsedResult
*/
DECLARE
@sql VARCHAR(2000)
,@where VARCHAR(1000)
,@i INT -- old posn in string
,@j INT -- match posn in string
,@k INT -- new start posn
,@len INT -- string length
,@search VARCHAR(500)
,@search2 VARCHAR(500)
,@fuzzy VARCHAR(1000)
,@keyword VARCHAR(500)
,@synonyms VARCHAR(255)
,@new_keywords VARCHAR(1000)
,@found INT
SET @keywords = LTRIM(RTRIM(@keywords))
SET @keywords = REPLACE(@keywords,'*',' ')
SET @keywords = REPLACE(@keywords,' AND ',' ')
SET @keywords = REPLACE(@keywords,' OR ',' ')
SET @keywords = REPLACE(@keywords,'"',' ')
SET @keywords = REPLACE(@keywords,'(',' ')
SET @keywords = REPLACE(@keywords,')',' ')
SET @keywords = REPLACE(@keywords,'o''','')
-- mcdonald's ==> mcdonald''s, escape out the ' which is a valid piece of punctuation
SET @keywords = REPLACE(@keywords,'''','''''')
-- fix é type characters
SET @found = CHARINDEX('é',@keywords)
IF @found > 0
IF @found = LEN(@keywords)
SET @keywords = REPLACE(@keywords,'é','')
ELSE
SET @keywords = REPLACE(@keywords,'é ','* ')
-- set proximity type
IF @proximity IS NULL
OR @proximity = ''
SET @proximity = 'NEAR'
SELECT
@i = 1 -- start of the first string
SELECT
@j = 0 -- end of the first string unknown
SELECT
@len = LEN(@keywords)
SELECT
@search = ''
SELECT
@fuzzy = ''
WHILE (@j <= @len)
BEGIN
SELECT
@k = @j + 1 -- New start posn
-- cut up the string into its individual words, split this
-- into its inflectional part and standard FTI search portion
SELECT
@j = CHARINDEX(' ',@keywords,@k)
-- Finish if no more found
IF (@j <= 0)
BEGIN
-- Add the last part of the string
SELECT
@search = @search + '"'
+ LTRIM(RTRIM(SUBSTRING(@keywords,@i,@len - @i + 1)))
+ '*"'
SELECT
@search2 = @search2 + '"'
+ LTRIM(RTRIM(SUBSTRING(@keywords,@i,@len - @i + 1)))
+ '"'
IF NOT SUBSTRING(@keywords,@k,@len - @k + 1)
IN ('of','and','at','a','the','&','it','for')
SELECT
@fuzzy = @fuzzy
+ 'FORMSOF(INFLECTIONAL,"'
+ LTRIM(RTRIM(SUBSTRING(@keywords,@k,@len - @k + 1)))
+ '")'
BREAK
END
IF (@j < @len)
BEGIN
IF (SUBSTRING(@keywords,@j - 1,1) <> ' ')
BEGIN
SELECT
@search = @search + '"'
+ LTRIM(RTRIM(SUBSTRING(@keywords,@i,@j - @i)))
+ '*" ' + @proximity + ' '
SELECT
@search2 = @search2 + '"'
+ LTRIM(RTRIM(SUBSTRING(@keywords,@i,@j - @i)))

SELECT

SELECT

END
END
END
IF SUBSTRING(@fuzzy,LEN(@fuzzy) - 2,3) = ' OR'
SET @fuzzy = SUBSTRING(@fuzzy,1,LEN(@fuzzy) - 2)
IF SUBSTRING(@fuzzy,LEN(@fuzzy) - 3,4) = ' AND'
SET @fuzzy = SUBSTRING(@fuzzy,1,LEN(@fuzzy) - 3)
-- Example: ("mcdonalds") OR ("mcdonalds*") OR (FORMSOF(INFLECTIONAL,"mcdonalds"))
SELECT
@search = '"' + @keywords + '" OR ' + '(' + @search2
+ ') OR (' + @search + ') OR (' + @fuzzy + ')'
SET @parsedstring = @search
SET CONCAT_NULL_YIELDS_NULL ON
END
Now the actual search:
CREATE PROCEDURE [dbo].[FullTextSearch]
@SearchTerm NVARCHAR(4000)
,@MinRelevance INT
,@MaxRows INT
,@NumRows INT = 0 OUTPUT
AS
BEGIN
/* Requires procedure FullTextParseSearchString to parse the search term(s) */
SET NOCOUNT ON
SET @SearchTerm = ISNULL(@SearchTerm,'')
SET @MinRelevance = ISNULL(@MinRelevance,10)
SET @MaxRows = ISNULL(@MaxRows,50)
DECLARE
@proximity VARCHAR(10)
,@tempstring NVARCHAR(4000)
,@ParsedSearchString NVARCHAR(4000)
SET @SearchTerm = REPLACE(REPLACE(REPLACE(REPLACE(@SearchTerm,'%',''),'"',''),'+',''),'&','')
SET @ParsedSearchString = '1=1 '
IF CHARINDEX(' OR ',@SearchTerm) > 0
SET @proximity = 'OR'
ELSE IF CHARINDEX(' AND ',@SearchTerm) > 0
SET @proximity = 'AND'
ELSE
SET @proximity = 'NEAR'
IF LTRIM(RTRIM(@SearchTerm)) <> ''
BEGIN
EXEC dbo.FullTextParseSearchString
@SearchTerm
,@proximity
,@tempstring OUTPUT
SET @ParsedSearchString = ISNULL(@ParsedSearchString,'') + ' OR (' + @tempstring + ')'
END
--for testing
--SELECT @proximity
--SELECT @ParsedSearchString
SET ROWCOUNT @MaxRows
SELECT
ROW_NUMBER() OVER (ORDER BY k.[RANK] DESC,a.PublishDate,a.Title) AS RowNum
,a.ArticleID
,a.Title
,a.BodyContent
,a.Author
,a.PublishDate
,k.[RANK] AS Relevance
FROM
dbo.Articles AS a
INNER JOIN
CONTAINSTABLE
(
dbo.Articles
,(*)
,@ParsedSearchString
)
AS k
ON a.ArticleID = k.
WHERE
k.[RANK] > @MinRelevance
AND a.isActive = 1
ORDER BY
k.[RANK] DESC
,a.PublishDate
,a.Title
SET ROWCOUNT 0
END
